Abstract
In the past few years, yeasts other than those belonging to the genus Saccharomyces have become increasingly important for industrial applications. Species such as Pichia pastoris, Hansenula polymorpha, Schizosaccharomyces pombe, Yarrowia lipolytica and Kluyveromyces lactis have been modified genetically and used for the production of heterologous proteins. For a number of additional yeasts such as Schwanniomyces occidentalis, Zygosaccharomyces rouxii, Trichosporon cutaneum, Pachysolen tannophilus, Pichia guilliermondii and members of the genus Candida genetic transformation systems have been worked out. Transformation was achieved using either dominant selection markers based on antibiotic resistance genes or auxotrophic markers in conjunction with cloned biosynthetic genes involved in amino acid or nucleotide metabolism.

Abstract
The expression in Saccharomyces cerevisiae and Schizosaccharomyces pombe of a cDNA copy of the Lipomyces kononenkoae IGC4052B alpha-amylase gene (LKA1), linked to the phosphoglycerate kinase gene (PGK1) promoter, resulted in the extracellular production of biologically active alpha-amylase (LKA1). However, transformation of S. cerevisiae and Schiz. pombe with a cosmid clone containing the complete genomic copy of LKA1, expressed from its native promoter, did not result in secretion of active alpha-amylase by any of the transformants. When the cDNA copy of LKA1 was expressed in S. cerevisiae under control of the wild-type L, kononenkoae promoter, biologically active alpha-amylase was secreted into the culture medium, indicating the recognition of the LKA1 promoter in S. cerevisiae. Sequence analysis of the GC-rich LKA1 promoter revealed canonical sequences that are homologous to the TATAAA, CAAT and CCAAT boxes and GCN4-binding sites that are present in several promoter sequences of S. cerevisiae. Primer extension analysis of LKA1 transcripts in L. kononenkoae indicated major initiation sites at nucleotides -64 and -65. S. cerevisiae and Schiz. pombe cells transformed with a plasmid containing the open reading frame of the genomic copy of LKA1, linked to the PGK1 promoter, did not produce alpha-amylase. Polymerase chain reaction mapping and sequence analysis revealed the presence of a 61-bp intron in the genomic copy of LKA1 that impaired synthesis of biologically active alpha-amylase in S. cerevisiae and Schiz. pombe. This intron contains donor, acceptor and branch sequences that correlate with the consensus sequences identified in the introns of split genes from Schiz. pombe and mammals. Pulsed-field gradient gel electrophoresis resolved at least eight chromosomal DNAs for L. kononenkoae IGC4052B and chromoblot analysis indicated that LKA1 is located on the second smallest chromosome, designated chromosome II.

Abstract
Studies of structure-function relationships in Na,K-ATPase require high yield expression of inactive mutations in cells without endogenous Na,K-ATPase activity. In this work we developed a host/vector system for expression of fully active pig Na,K-ATPase as well as the inactive mutations D369N and D807N at high levels in Saccharomyces cerevisiae. The alpha 1- and beta 1-subunit cDNAs were inserted into a single 2-microns-based plasmid with a high and regulatable copy number and strong galactose-inducible promoters allowing for stoichiometric alterations of gene dosage. The protease-deficient host strain was engineered to express high levels of GAL4 transactivating protein, thereby causing a 10-fold increase in expression to 32,500 +/- 3,000 [3H]ouabain sites/cell. In one bioreactor run 150-200 g of yeast were produced with 54 +/- 5 micrograms of Na,K-pump protein/g of cells. Through purification in membrane bound form the activity of the recombinant Na,K-ATPase was increased to 42-50 pmol/mg of protein. The Na,K dependence of ATP hydrolysis and the molar activity (4,500-7,000 min-1) were close to those of native pig kidney Na,K-ATPase. Mutations to the phosphorylation site (D369N) or presumptive cation sites (D807N), both devoid of Na,K-ATPase activity, were expressed in the yeast membrane at the same alpha-subunit concentration and [3H]ouabain binding capacity as the wild type Na,K-ATPase. The high yield and absence of endogenous activity allowed assay of [3H]ATP binding at equilibrium, demonstrating a remarkable 18-fold increase in affinity for ATP in consequence of reducing the negative charge at the phosphorylation site (D369N).

Abstract
Determination of the structure of integral membrane proteins is a challenging task that is essential to understand how fundamental biological processes (such as photosynthesis, respiration and solute translocation) function at the atomic level. Crystallisation of membrane proteins in 3D has led to the determination of four atomic resolution structures [photosynthetic reaction centres (Allenet al. 1987; Changet al. 1991; Deisenhofer & Michel, 1989; Ermleret al. 1994); porins (Cowanet al. 1992; Schirmeret al. 1995; Weisset al. 1991); prostaglandin H2synthase (Picotet al. 1994); light harvesting complex (McDermottet al. 1995)], and crystals of membrane proteins formed in the plane of the lipid bilayer (2D crystals) have produced two more structures [bacteriorhodopsin (Hendersonet al. 1990); light harvesting complex (Kühlbrandtet al. 1994)].

Abstract
The toxicity of HBsAg in the secretion pathway of pep4 strains can be progressively reduced in modified SD media containing lower concentrations of ammonium sulphate. A procedure, combining a reduction of ammonium sulphate concentration in SD media with the disruption of the PEP4 gene of the host strain, was developed to enrich transformants which are not inhibited by HBsAg expressed in the secretion pathway. Abnormal growth of these non-inhibited transformants is characterized by the enlargement of cell morphology, a transition to pseudohyphal-like growth in nitrogen-starved media, an increase in HBsAg particle production, and the enhancement of growth rate in liquid media. This suggests a new approach to overcoming the toxicity of heterologous protein in the yeast secretion pathway.

Abstract
We have developed a novel expression system that allows the fission yeast, Schizosaccharomyces pombe, to be used for the efficient overproduction of heterologous proteins. As an example of the utility of this system, human lipocortin I was expressed to 50 percent of soluble protein, and 150 mg of highly purified material was obtained from 10 grams of wet cell paste. Expression of lipocortin I was driven by the human cytomegalovirus (hCMV) promoter in a vector that also contains a neomycin resistance gene (neo) under the control of the SV40 early promoter, permitting selection for increasing copy-number with increasing concentrations of the antibiotic G418. The purified protein was equivalent to its native counterpart with respect to antigenicity and biochemical properties such as phospholipase A2 inhibition, actin binding and N-terminal acetylation. We have also used this system to produce comparable amounts of other proteins including rat arginase, rat NDP-kinase and human interleukin-6.

Abstract
The Saccharomyces cerevisiae Lanosterol 14 alpha-demethylase (14DM) gene was overexpressed in S. cerevisiae using promoter sequences of the highly expressed S. cerevisiae glyceraldehyde-3-phosphate dehydrogenase (TDH3) gene. To investigate factors affecting 14DM overproduction, the levels of 14DM-specific RNAs, apoprotein, and heme protein, respectively, were determined and the 14DM-specific RNA levels compared with the RNA levels originating from the endogenous TDH gene(s). The quantitative measurements revealed that the 14DM steady-state RNA levels reached were some three- to five-fold below the theoretically expected values. With a view towards further improving expression of the 14DM gene, the spacing between the TDH3 promoter and the AUG was adjusted precisely and to rule out possible toxic effects exerted by the 14DM protein, the TDH3 promoter was placed under galactose regulation by introducing an UASG segment. Furthermore, the effects of the gene copy number on 14DM overproduction were investigated. From the analysis of the improved expression constructs five conclusions could be reached: (1) expression from the native 14DM gene is comparable to the expression driven by the TDH3 promoter-14DM fusion construct on single copy plasmid vectors; (2) expression from the TDH3 promoter-14DM construct on single-copy vectors is nearly as efficient as expression from the corresponding endogenous TDH3 gene; (3) the gene copy number has an effect on the relative expression levels of the TDH3 promoter-14DM constructs; (4) the steady-state amounts of protein produced are very nearly proportional to gene dosage; and (5) protein toxicity does not have a major impact on 14DM production. The maximum yield of 14DM was in the order of 7% of the total yeast protein and the maximum production of functional 14DM heme protein appears to be limited by the availability of heme.

Abstract
We have studied the activity of yeast PGK promoter in E. coli at different temperatures using lacZ as the reporter gene. The B-galactosidase activity was found to be less at 42 degrees C than at 30 degrees C. Northern blot analysis showed that the level of lacZ transcript was less in recombinant cells grown at 42 degrees C, whereas plasmid copy number per cell was more as compared to recombinant cells grown at 30 degrees C. Data suggest that the yeast PGK promoter is less active at 42 degrees C and that this activity is regulated at the level of transcription.

Abstract
A general expression vector (pMB332) for the fission yeast Schizosaccharomyces pombe was constructed. The heterologous gene expression is driven by the S. pombe alcohol dehydrogenase (adh) promoter. Transcription termination signals were isolated from the S. pombe actin gene. The vectors carry the Saccharomyces cerevisiae Ura3 gene, which complements the S. pombe ura4 mutation. The plasmid stability is conferred by the S. pombe ars and stb elements isolated from pFL120 [(1983) Cell 32, 371-377]. An 'ATG' vector (pMB340) was created, which allows the expression of protein fragments fused to a translational start codon downstream of the adh promoter. The function of this vector system is shown by the production of the human blood coagulation protein factor XIIIa.
