Abstract
Monoclonal antibodies (mAbs) are laboratory-based engineered protein molecules with a monovalent affinity or multivalent avidity towards a specific target or antigen, which can mimic natural antibodies that are produced in the human immune systems to fight against detrimental pathogens. The recombinant mAb is one of the most effective classes of biopharmaceuticals produced in vitro by cloning and expressing synthetic antibody genes in a suitable host. Yeast is one of the potential hosts among others for the successful production of recombinant mAbs. However, there are very few yeast-derived mAbs that got the approval of the regulatory agencies for direct use for treatment purposes. Certain challenges encountered by yeasts for recombinant antibody productions need to be overcome and a few considerations related to antibody structure, host engineering, and culturing strategies should be followed for the improved production of mAbs in yeasts. In this review, the drawbacks related to the metabolic burden of the host, culturing conditions including induction mechanism and secretion efficiency, solubility and stability, downstream processing, and the pharmacokinetic behavior of the antibody are discussed, which will help in developing the yeast hosts for the efficient production of recombinant mAbs.

Yarrowia lipolytica Strains and Their Biotechnological Applications: How Natural Biodiversity and Metabolic Engineering Could Contribute to Cell Factories Improvement. J Fungi (Basel) 2021; 7:jof7070548. [PMID: 34356927 PMCID: PMC8307478 DOI: 10.3390/jof7070548] [Citation(s) in RCA: 38] [Impact Index Per Article: 12.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2021] [Revised: 07/01/2021] [Accepted: 07/05/2021] [Indexed: 11/20/2022] Open
Abstract
Among non-conventional yeasts of industrial interest, the dimorphic oleaginous yeast Yarrowia lipolytica appears as one of the most attractive for a large range of white biotechnology applications, from heterologous proteins secretion to cell factories process development. The past, present and potential applications of wild-type, traditionally improved or genetically modified Yarrowia lipolytica strains will be resumed, together with the wide array of molecular tools now available to genetically engineer and metabolically remodel this yeast. The present review will also provide a detailed description of Yarrowia lipolytica strains and highlight the natural biodiversity of this yeast, a subject little touched upon in most previous reviews. This work intends to fill this gap by retracing the genealogy of the main Yarrowia lipolytica strains of industrial interest, by illustrating the search for new genetic backgrounds and by providing data about the main publicly available strains in yeast collections worldwide. At last, it will focus on exemplifying how advances in engineering tools can leverage a better biotechnological exploitation of the natural biodiversity of Yarrowia lipolytica and of other yeasts from the Yarrowia clade.

Abstract
INTRODUCTION Yeast humanization, ranging from a simple point mutation to substitution of yeast gene(s) or even a complete pathway by human counterparts has enormously expanded yeast biomedical applications. AREAS COVERED General and patent-oriented insights into the application of native and humanized yeasts for production of human glycoproteins (gps) and antibodies (Abs), toxicity/mutagenicity assays, treatments of gastrointestinal (GI) disorders and potential drug delivery as a probiotic (with emphasis on Saccharomyces bulardii) and studies on human diseases/cancers and screening effective drugs. EXPERT OPINION Humanized yeasts cover the classical advantageous features of a 'microbial eukaryote' together with advanced human cellular processes. These unique characteristics would permit their use in the production of functional and stable therapeutic gps and Abs in lower prices compared to mammalian (CHO) production-based systems. Availability of yeasts humanized for cytochrome P450 s will expand their application in metabolism-related chemical toxicity assays. Engineered S. bulardii for expression of human proteins might expand its application by synergistically combining the probiotic activity with the treatment of metabolic diseases such as phenylketonuria via GI-delivery. Yeast models of human diseases will facilitate rapid functional/phenotypic characterization of the disease-producing mutant genes and screening of the therapeutic compounds using yeast-based high-throughput research techniques (Yeast one/two hybrid systems) and viability assays.

Abstract
Background The secretory production of recombinant proteins in yeast simplifies isolation and purification but also faces possible complications due to the complexity of the secretory pathway. Therefore, correct folding, maturation and intracellular transport of the recombinant proteins are important processing steps with a higher effort needed for complex and large proteins. The aim of this study was to elucidate the secretion potential of Yarrowia lipolytica for low and high molecular weight β-glycosidases in a comparative cultivation approach. Results A low sized β-glucosidase from Pyrococcus furiosus (CelB; 55 kDa) and a large sized β-galactosidase isolated from the metagenome (M1; 120 kDa) were integrated into the acid extracellular protease locus using the CRISPR–Cas9 system to investigate the size dependent secretion of heterologous proteins in Y. lipolytica PO1f. The recombinant strains were cultivated in the bioreactor for 78 h and the extra- and intracellular enzyme activities were determined. The secretion of CelB resulted in an extracellular volumetric activity of 187.5 µkatoNPGal/Lmedium, while a volumetric activity of 2.98 µkatoNPGal/Lmedium was measured during the M1 production. However, when the amount of functional intra- and extracellular enzyme was investigated, the high molecular weight M1 (85%) was secreted more efficiently than CelB (27%). Real-time PCR experiments showed a linear correlation between the transcript level and extracellular activity for CelB, while a disproportional high mRNA level was observed regarding M1. Interestingly, mass spectrometry data revealed the unexpected secretion of two endogenous intracellular glycolytic enzymes, which is reported for the first time for Y. lipolytica. Conclusion The results of this study provide deeper insights into the secretion potential of Y. lipolytica. A secretion limitation for the low-size CelB was observed, while the large size M1 enzyme was produced in lower amounts but was secreted efficiently. It was shown for the first time that Y. lipolytica is a promising host for the secretion of heterologous high molecular weight proteins (> 100 kDa), although the total secreted amount has to be increased further.

Heterologous expression of an α-amylase inhibitor from common bean (Phaseolus vulgaris) in Kluyveromyces lactis and Saccharomyces cerevisiae. Microb Cell Fact 2017; 16:110.

Abstract
Background Phaseolamin or α-amylase inhibitor 1 (αAI) is a glycoprotein from common beans (Phaseolus vulgaris L.) that inhibits some insect and mammalian α-amylases. Several clinical studies support the beneficial use of bean αAI for control of diabetes and obesity. Commercial extracts of P. vulgaris are available but their efficacy is still under question, mainly because some of these extracts contain antinutritional impurities naturally present in bean seeds and also exhibit a lower specific activity αAI. The production of recombinant αAI allows to overcome these disadvantages and provides a platform for the large-scale production of pure and functional αAI protein for biotechnological and pharmaceutical applications. Results A synthetic gene encoding αAI from the common bean (Phaseolus vulgaris cv. Pinto) was codon-optimised for expression in yeasts (αAI-OPT) and cloned into the protein expression vectors pKLAC2 and pYES2. The yeasts Kluyveromyces lactis GG799 (and protease deficient derivatives such as YCT390) and Saccharomyces cerevisiae YPH499 were transformed with the optimised genes and transformants were screened for expression by antibody dot blot. Recombinant colonies of K. lactis YCT390 that expressed and secreted functional αAI into the culture supernatants were selected for further analyses. Recombinant αAI from K. lactis YCT390 was purified using anion-exchange and affinity resins leading to the recovery of a functional inhibitor. The identity of the purified αAI was confirmed by mass spectrometry. Recombinant clones of S. cerevisiae YPH499 expressed functional αAI intracellularly, but did not secrete the protein. Conclusions This is the first report describing the heterologous expression of the α-amylase inhibitor 1 (αAI) from P. vulgaris in yeasts. We demonstrated that recombinant strains of K. lactis and S. cerevisiae expressed and processed the αAI precursor into mature and active protein and also showed that K. lactis secretes functional αAI.

Abstract
The increasing demand for recombinant vaccine antigens or immunotherapeutic molecules calls into question the universality of current protein expression systems. Vaccine production can require relatively low amounts of expressed materials, but represents an extremely diverse category consisting of different target antigens with marked structural differences. In contrast, monoclonal antibodies, by definition share key molecular characteristics and require a production system capable of very large outputs, which drives the quest for highly efficient and cost-effective systems. In discussing expression systems, the primary assumption is that a universal production platform for vaccines and immunotherapeutics will unlikely exist. This review provides an overview of the evolution of traditional expression systems, including mammalian cells, yeast and E.coli, but also alternative systems such as other bacteria than E. coli, transgenic animals, insect cells, plants and microalgae, Tetrahymena thermophila, Leishmania tarentolae, filamentous fungi, cell free systems, and the incorporation of non-natural amino acids.

Abstract
Recombinant antibodies are highly specific detection probes in research, diagnostics, and have emerged over the last two decades as the fastest growing class of therapeutic proteins. Antibody generation has been dramatically accelerated by in vitro selection systems, particularly phage display. An increasing variety of recombinant production systems have been developed, ranging from Gram-negative and positive bacteria, yeasts and filamentous fungi, insect cell lines, mammalian cells to transgenic plants and animals. Currently, almost all therapeutic antibodies are still produced in mammalian cell lines in order to reduce the risk of immunogenicity due to altered, non-human glycosylation patterns. However, recent developments of glycosylation-engineered yeast, insect cell lines, and transgenic plants are promising to obtain antibodies with "human-like" post-translational modifications. Furthermore, smaller antibody fragments including bispecific antibodies without any glycosylation are successfully produced in bacteria and have advanced to clinical testing. The first therapeutic antibody products from a non-mammalian source can be expected in coming next years. In this review, we focus on current antibody production systems including their usability for different applications.

Abstract
α-Ketoglutarate (α-KG) is an important intermediate in the tricarboxylic acid (TCA) cycle and has an important role in the regulation of the balance between carbon and nitrogen metabolism in most microorganisms. In previous research, a thiamine-auxotrophic yeast for α-KG overproduction was screened and named as Yarrowia lipolytica WSH-Z06. To enhance α-KG production and reduce by-product (mainly pyruvate) accumulation, the cofactor metabolism was regulated to redistribute the carbon flux from pyruvate to α-KG. The acetyl-CoA synthetase gene, ACS1, from Saccharomyces cerevisiae and the ATP-citrate lyase gene, ACL, from Mus musculus were expressed to regulate the acetyl-CoA metabolism in Y. lipolytica WSH-Z06. The resultant strains were designated as Y. lipolytica-ACS1 and Y. lipolytica-ACL, respectively. Both of the ACS1 and ACL genes could increase the level of acetyl-CoA and enhance the α-KG production. In a 3-L jar fermenter, the highest yield of α-KG in Y. lipolytica-ACL reached up to 56.5 g L(-1) with an obvious decrease of pyruvate accumulation from 35.1 g L(-1) to 20.2 g L(-1). This study demonstrated that enhancing the acetyl-CoA availability could effectively increase the α-KG production in Y. lipolytica.

Abstract
Oleaginous yeast Yarrowia lipolytica is an important host for the production of lipid-derived compounds or heterologous proteins. Selection of strong promoters and effective expression systems is critical for heterologous protein secretion. To search for a strong promoter in Y. lipolytica, activities of FBA1, TDH1 and GPM1 promoters were compared to that of TEF1 promoter by constructing GUS reporter fusions. The FBA1 promoter activity was 2.2 and 5.5 times stronger than the TDH1 and GPM1 promoters, respectively. The FBA1IN promoter (FBA1 sequence of -826 to +169) containing an intron (+64 to +165) showed five-fold higher expression than the FBA1 promoter (-831 to -1). The transcriptional enhancement by the 5'-region within the FBA1 gene was confirmed by GPM1::FBA1 chimeric promoter construction. Using the strong FBA1IN promoter, four different S. cerevisiae SUC2 expression cassettes were tested for the SUC+ phenotype in Y. lipolytica. Functional invertase secretion was facilitated by the Xpr2 prepro-region with an additional 13 amino acids of mature Xpr2, or by the native Suc2 signal sequence. However, these two secretory signals in tandem, or the mature Suc2 with no secretory signal, did not direct secretion of functional invertase. Unlike previously reported Y. lipolytica SUC+ strains, our engineered stains secreted most of invertase into the medium.

Abstract
The acquisition of the correct folding of membrane proteins is a crucial process that involves several steps from the recognition of nascent protein, its targeting to the endoplasmic reticulum membrane, its insertion, and its sorting to its final destination. Yarrowia lipolytica is a hemiascomycetous dimorphic yeast and an alternative eukaryotic yeast model with an efficient secretion pathway. To better understand the quality control of membrane proteins, we constructed a model system based on the uracil permease. Mutated forms of the permease were stabilized and retained in the cell and made the strains resistant to the 5-fluorouracil drug. To identify proteins involved in the quality control, we separated proteins extracted in nondenaturing conditions on blue native gels to keep proteins associated in complexes. Some gel fragments where the model protein was immunodetected were subjected to mass spectrometry analysis. The proteins identified gave a picture of the folding proteome, from the translocation across the endoplasmic reticulum membrane, the folding of the proteins, to the vesicle transport to Golgi or the degradation via the proteasome. For example, EMC complex, Gsf2p or Yet3p, chaperone membrane proteins of the endoplasmic reticulum were identified in the Y. lipolytica native proteome.

Abstract
In this work, we investigated the effect of codon bias and consensus sequence (CACA) at the translation initiation site on the expression level of heterologous proteins in Yarrowia lipolytica; human interferon alpha 2b (hIFN-α2b) was studied as an example. A codon optimized hIFN-α2b gene was synthesized according to the frequency of codon usage in Y. lipolytica. Both wild-type (IFN-wt) and optimized hIFN-α2b (IFN-op) genes were expressed under the control of a strong inducible promoter acyl-co-enzyme A oxidase (POX2). Protein secretion was directed by the targeting sequence of the extracellular lipase (LIP2): pre-proLIP2. Codon optimization increased protein production by 11-fold, whereas the insertion of CACA sequence upstream of the initiation codon of IFN-op construct resulted in 16.5-fold increase of the expression level; this indicates that translational efficiency plays an important part in the increase of hIFN-α2b production level. The replacement of the pre-proLIP2 signal secretion with the LIP2 pre-region sequence followed by the X-Ala/X-Pro stretch but without the pro-region also increased the secretion of the target protein by twofold, suggesting therefore that the LIP2 pro-region is not necessary for extracellular secretion of small heterologous proteins in Yarrowia lipolytica.

Abstract
The Aspergillus aculeatus MRC11624 man1 gene, encoding an endo-beta-1,4-mannanase, was cloned and expressed in the promising heterologous enzyme producer, the ascomycetous yeast Yarrowia lipolytica. Both single- and multi-copy transformants were constructed, and the secretion of the enzyme was evaluated as an in-frame fusion with the LIP2 secretion signal, as well as with its natural secretion signal. In shake-flask analysis, the highest volumetric enzyme activity (13,073 nkat/ml) and specific enzyme activity (1,020 nkat/(mg dcw)) were obtained with a multi-copy integrant utilizing beta-mannanase's own secretion signal. The best beta-mannanase-producing strain was subsequently evaluated in batch fermentation and resulted in a maximum volumetric enzyme activity of 6,719 nkat/ml. Fed batch fermentations resulted in a 3.9-fold increase in volumetric enzyme activity compared with batch fermentation, and a maximum titre of 26,139 nkat/ml was obtained. The results reported in this study indicate that Y. lipolytica is a promising producer of A. aculeatus beta-mannanase, producing higher beta-mannanase activity than that of recombinant Saccharomyces cerevisiae or Aspergillus niger when cultivated in shake flasks, which is encouraging for the use of the enzyme in industrial processes such as extraction of vegetable oil from leguminous seeds and the reduction in viscosity of coffee extracts.

Abstract
Antibodies (Abs) are some of the most powerful tools in therapy and diagnostics and are currently one of the fastest growing classes of therapeutic molecules. Recombinant antibody (rAb) fragments are becoming popular therapeutic alternatives to full length monoclonal Abs since they are smaller, possess different properties that are advantageous in certain medical applications, can be produced more economically and are easily amendable to genetic manipulation. Single-chain variable fragment (scFv) Abs are one of the most popular rAb format as they have been engineered into larger, multivalent, bi-specific and conjugated forms for many clinical applications. This review will show the tremendous versatility and importance of scFv fragments as they provide the basic antigen binding unit for a multitude of engineered Abs for use as human therapeutics and diagnostics.

Abstract
BACKGROUND Protein secretion is a universal cellular process involving vesicles which bud and fuse between organelles to bring proteins to their final destination. Vesicle budding is mediated by protein coats; vesicle targeting and fusion depend on Rab GTPase, tethering factors and SNARE complexes. The Génolevures II sequencing project made available entire genome sequences of four hemiascomycetous yeasts, Yarrowia lipolytica, Debaryomyces hansenii, Kluyveromyces lactis and Candida glabrata. Y. lipolytica is a dimorphic yeast and has good capacities to secrete proteins. The translocation of nascent protein through the endoplasmic reticulum membrane was well studied in Y. lipolytica and is largely co-translational as in the mammalian protein secretion pathway. RESULTS We identified S. cerevisiae proteins involved in vesicular secretion and these protein sequences were used for the BLAST searches against Génolevures protein database (Y. lipolytica, C. glabrata, K. lactis and D. hansenii). These proteins are well conserved between these yeasts and Saccharomyces cerevisiae. We note several specificities of Y. lipolytica which may be related to its good protein secretion capacities and to its dimorphic aspect. An expansion of the Y. lipolytica Rab protein family was observed with autoBLAST and the Rab2- and Rab4-related members were identified with BLAST against NCBI protein database. An expansion of this family is also found in filamentous fungi and may reflect the greater complexity of the Y. lipolytica secretion pathway. The Rab4p-related protein may play a role in membrane recycling as rab4 deleted strain shows a modification of colony morphology, dimorphic transition and permeability. Similarly, we find three copies of the gene (SSO) encoding the plasma membrane SNARE protein. Quantification of the percentages of proteins with the greatest homology between S. cerevisiae, Y. lipolytica and animal homologues involved in vesicular transport shows that 40% of Y. lipolytica proteins are closer to animal ones, whereas they are only 13% in the case of S. cerevisiae. CONCLUSION These results provide further support for the idea, previously noted about the endoplasmic reticulum translocation pathway, that Y. lipolytica is more representative of vesicular secretion of animals and other fungi than is S. cerevisiae.

Abstract
Kluyveromyces lactis is both scientifically and biotechnologically one of the most important non-Saccharomyces yeasts. Its biotechnological significance builds on its history of safe use in the food industry and its well-known ability to produce enzymes like lactase and bovine chymosin on an industrial scale. In this article, we review the various strains, genetic techniques and molecular tools currently available for the use of K. lactis as a host for protein expression. Additionally, we present data illustrating the recent use of proteomics studies to identify cellular bottlenecks that impede heterologous protein expression.

Abstract
The enzymatic degradation of L-methionine and the subsequent formation of volatile sulfur compounds (VSCs) are essential for the development of the typical flavor in cheese. In the yeast Yarrowia lipolytica, the degradation of L-methionine was accompanied by the formation of the transamination product 4-methylthio-2-oxobutyric acid. A branched-chain aminotransferase gene (YlBCA1) of Y. lipolytica was amplified, and the L-methionine-degrading activity and the aminotransferase activity were measured in a genetically modified strain and compared to those of the parental strain. Our work shows that L-methionine degradation via transamination is involved in formation of VSCs in Y. lipolytica.

Abstract
Yeasts combine the ease of genetic manipulation and fermentation of a microbial organism with the capability to secrete and to modify proteins according to a general eukaryotic scheme. Yeasts thus provide attractive platforms for the production of recombinant proteins. Here, four important species are presented and compared: the methylotrophic Hansenula polymorpha and Pichia pastoris, distinguished by an increasingly large track record as industrial platforms, and the dimorphic species Arxula adeninivorans and Yarrrowia lipolytica, not yet established as industrial platforms, but demonstrating promising technological potential, as discussed in this article.

Abstract
Pycnoporus cinnabarinus lac1 gene was expressed in Yarrowia lipolytica. Different secretion signals and culture media were tested. Production was correlated to both culture growth rate and cell morphology (highest at low growth rate, without mycelium). Recombinant laccase was characterized (immunodetection, N-terminal sequencing) and purified. Production was estimated to 20 mgl(-1) in a bioreactor. Thus, complex metalloenzymes can be produced in Yarrowia, assuming some control of host physiology. Lac1p production was compared in Yarrowia, Pichia and Aspergillus: recombinant proteins were active, but host systems differed in transformation efficiency, production, and glycosylation. If not the best producer, Yarrowia offers very high transformation efficiencies, allowing the genetic engineering of laccases for industrial applications.

Abstract
Screening for genes affecting super-secreting phenotype of the over-secreting mutant of Kluyveromyces lactis resulted in isolation of the gene named KlMNN10, sharing high homology with Saccharomyces cerevisiae MNN10. The disruption of the KlMNN10 in Kluyveromyces lactis, as well as of MNN10 and MNN11 in Saccharomyces cerevisiae, conferred the super-secreting phenotype. MNN10 isolated from Saccharomyces cerevisiae suppressed the super-secretion phenotype in Kluyveromyces lactis klmnn10, as did the homologous KlMNN10. The genes MNN10 and MNN11 of Saccharomyces cerevisiae encode mannosyltransferases responsible for the majority of the alpha-1,6-polymerizing activity of the mannosyltransferase complex. These data agree with the view that the structure of glycoproteins in a yeast cell wall strongly influences the release of homologous and heterologous proteins in the medium. The set of genes namely the suppressors of the over-secreting phenotype, could be attractive for further analysis of gene functions, over-secreting mechanisms and for construction of new strains optimized for heterologous protein secretion. KlMNN10 has EMBL accession no. AJ575132.

Abstract
The secreted production of heterologous proteins in Kluyveromyces lactis was studied. A glucoamylase (GAA) from the yeast Arxula adeninivorans was used as a reporter protein for the study of the secretion efficiencies of several wild-type and mutant strains of K. lactis. The expression of the reporter protein was placed under the control of the strong promoter of the glyceraldehyde-3-phosphate dehydrogenase of Saccharomyces cerevisiae. Among the laboratory strains tested, strain JA6 was the best producer of GAA. Since this strain is known to be highly sensitive to glucose repression and since this is an undesired trait for biomass-oriented applications, we examined heterologous protein production by using glucose repression-defective mutants isolated from this strain. One of them, a mutant carrying a dgr151-1 mutation, showed a significantly improved capability of producing heterologous proteins such as GAA, human serum albumin, and human interleukin-1beta compared to the parent strain. dgr151-1 is an allele of RAG5, the gene encoding the only hexokinase present in K. lactis (a homologue of S. cerevisiae HXK2). The mutation in this strain was mapped to nucleotide position +527, resulting in a change from glycine to aspartic acid within the highly conserved kinase domain. Cells carrying the dgr151-1 allele also showed a reduction in N- and O-glycosylation. Therefore, the dgr151 strain may be a promising host for the production of heterologous proteins, especially when the hyperglycosylation of recombinant proteins must be avoided.

Abstract
In this study, the identification and characterization of theYarrowia lipolyticahomologues ofSaccharomyces cerevisiaeα-1,6-mannosyltransferases Anp1p and Och1p, designated YlAnl1p and YlOch1p, are described. In order to confirm the function of theY. lipolyticaproteins, including the previously isolated YlMnn9p, in theN-glycosylation pathway, a phenotypic analysis of the disrupted strains ΔYlmnn9, ΔYlanl1, ΔYloch1, ΔYlanl1ΔYlmnn9and ΔYlmnn9ΔYloch1was performed. Disruption of theYlMNN9,YlANL1andYlOCH1genes caused an increased sensitivity to SDS, compatible with a glycosylation defect, and to Calcofluor White, characteristic of cell-wall defects. Moreover, Western-blot analysis of a heterologous glycosylated protein confirmed a direct role of YlMnn9p and YlAnl1p in theN-glycosylation process. These mutant strains, ΔYlmnn9, ΔYlanl1, ΔYloch1, ΔYlanl1ΔYlmnn9and ΔYlmnn9ΔYloch1may thus be used to establish a model for theY. lipolyticaN-linked glycosylation pathway.

Abstract
The production of heterologous proteins is a research field of high interest, with both academic and commercial applications. Yeasts offer a number of advantages as host systems, and, among them, Yarrowia lipolytica appears as one of the most attractive. This non-conventional dimorphic yeast exhibits a remarkable regularity of performance in the efficient secretion of various heterologous proteins. This review presents the main characteristics of Y. lipolytica, and the genetic and molecular tools available in this yeast. A particular emphasis is given to newly developed tools such as efficient promoters, a non-homologous integration method, and an amplification system using defective selection markers. A table recapitulates the 42 heterologous proteins produced until now in Y. lipolytica. A few relevant examples are exposed in more detail, in order to illustrate some peculiar points of the Y. lipolytica physiology, and to offer a comparison with other production systems. This amount of data demonstrates the global reliability and versatility of Y. lipolytica as a host for heterologous production.

Abstract
Molecular tools for the production of heterologous proteins and metabolic engineering applications of the non-conventional yeast Zygosaccharomyces bailii were developed. The combination of Z. bailii's resistance to relatively high temperature, osmotic pressure and low pH values, with a high specific growth rate renders this yeast potentially interesting for exploitation for biotechnological purposes as well as for the understanding of the biological phenomena and mechanisms underlying the respective resistances. Looking forward to these potential applications, here we present the tools required for the production and the secretion of different heterologous proteins, and one example of a metabolic engineering application of this non-conventional yeast, employing the newly developed molecular tools.

Abstract
Recombinant antibodies currently represent over 30% of biopharmaceuticals in clinical trials, highlighted by the recent Food and Drug Administration (FDA) approvals of Zevalin(TM) (ibritumomab-tiuxetan; IDEC Pharmaceuticals, San Dieago, CA, USA) for cancer radioimmunotherapy and Humira(TM) (adalimumab; Abbott Laboratories, IL, USA) for rheumatoid arthritis. Together, these FDA approvals have excited the biotechnology industry, particularly since sales of recombinant antibodies are increasing rapidly to a predicted US dollar 4 billion per annum worldwide in 2003. To date, 10 engineered therapeutic antibodies have gained FDA approval and many others are in Phase III trials. Many recent FDA-approved antibodies are simple molecular designs that have taken 10 years to be developed into effective therapeutic reagents. Emerging new technologies have created a vast range of recombinant, antibody-based reagents, which specifically target clinical biomarkers of disease. Radiolabelling of antibodies has increased their potential for cancer imaging and targeting. Recombinant antibodies have also been reduced in size and rebuilt into multivalent molecules for higher affinity. In addition, antibodies have been fused with many molecules, including toxins, enzymes, drugs and viruses, for prodrug therapy, cancer treatment and gene delivery. Recombinant antibody technology has enabled clever manipulations in the construction of complex in vitro libraries for the selection of high-affinity reagents against refractory targets. Furthermore, innovative affinity maturation methods have been developed which enable rapid selection of extremely high-affinity reagents. This review focuses on developments in the last 12 months and describes the latest developments in the design, production and clinical use of recombinant antibodies for cancer diagnosis and therapy.

Abstract
Antibodies represent an interesting protein framework on which catalytic functions can be grafted. In previous studies, we have reported the characterization of the catalytic antibody 4B2 obtained on the basis of the "bait and switch" strategy which catalyzes two different chemical reactions: the allylic isomerization of beta,gamma-unsaturated ketones and the Kemp elimination. We have cloned the antibody 4B2 and expressed it as a single-chain Fv (scFv) fragment in different expression systems, Escherichia coli and two yeasts species, in order to elicit the most suitable system to study its catalytic activity. The scFv4B2 was secreted as an active form in the culture medium of Pichia pastoris and Kluyveromyces lactis, which led respectively to 4 and 1.3mg/l after purification. In E. coli, different strategies were investigated to increase the cytoplasmic soluble fraction, which resulted, in all cases, in the expression of a low amount of functional antibodies. By contrast, substantial amount of scFv4B2 could be purified when it was expressed as inclusion bodies (12mg/l) and submitted to an in vitro refolding process. Its catalytic activity was measured and proved to be comparable to that of the whole IgG. However, the instability of the scFv4B2 in solution prevented from an exhaustive characterization of its activity and stabilization of this protein appears to be essential before designing strategies to improve its catalytic activity.
