Abstract
In nature 2-deoxy-D-ribose-5-phosphate aldolase (DERA) catalyses the reversible formation of 2-deoxyribose 5-phosphate from D-glyceraldehyde 3-phosphate and acetaldehyde. In addition, this enzyme can use acetaldehyde as the sole substrate, resulting in a tandem aldol reaction, yielding 2,4,6-trideoxy-D-erythro-hexapyranose, which spontaneously cyclizes. This reaction is very useful for the synthesis of the side chain of statin-type drugs used to decrease cholesterol levels in blood. One of the main challenges in the use of DERA in industrial processes, where high substrate loads are needed to achieve the desired productivity, is its inactivation by high acetaldehyde concentration. In this work, the utility of different variants of Pectobacterium atrosepticum DERA (PaDERA) as whole cell biocatalysts to synthesize 2-deoxyribose 5-phosphate and 2,4,6-trideoxy-D-erythro-hexapyranose was analysed. Under optimized conditions, E. coli BL21 (PaDERA C-His AA C49M) whole cells yields 99 % of both products. Furthermore, this enzyme is able to tolerate 500 mM acetaldehyde in a whole-cell experiment which makes it suitable for industrial applications.

Abstract
AICA (5'-aminoimidazole-4-carboxamide) ribonucleotides with different phosphorylation levels are the pharmaceutically active metabolites of AICA nucleoside-based drugs. The chemical synthesis of AICA ribonucleotides with defined phosphorylation is challenging and expensive. In this study, we describe two enzymatic cascades to synthesize AICA derivatives with defined phosphorylation levels from the corresponding nucleobase and the co-substrate phosphoribosyl pyrophosphate. The cascades are composed of an adenine phosphoribosyltransferase from Escherichia coli (EcAPT) and different polyphosphate kinases: polyphosphate kinase from Acinetobacter johnsonii (AjPPK), and polyphosphate kinase from Meiothermus ruber (MrPPK). The role of the EcAPT is to bind the nucleobase to the sugar moiety, while the kinases are responsible for further phosphorylation of the nucleotide to produce the desired phosphorylated AICA ribonucleotide. The selected enzymes were characterized, and conditions were established for two enzymatic cascades. The diphosphorylated AICA ribonucleotide derivative ZDP, synthesized from the cascade EcAPT/AjPPK, was produced with a conversion up to 91 %. The EcAPT/MrPPK cascade yielded ZTP with conversion up to 65 % with ZDP as a side product.

Abstract
Nowadays, enzymatic synthesis of nucleotides is an efficient and sustainable alternative to chemical methodologies. In this regard, after the biochemical characterization of wild-type and mutant uracil phosphoribosyltransferases from Toxoplasma gondii (TgUPRT, TgUPRT2, and TgUPRT3), TgUPRT2 was selected as the optimal candidate (69.5 IU mg-1, UMP synthesis) for structure-guided immobilization onto Ni2+ chelate (MNiUPRT2) and onto glutaraldehyde-activated microparticles (MGlUPRT2). Among resulting derivatives, MNiUPRT23 (6127 IU g-1biocat; 92% retained activity; 3-5 fold enhanced stability at 50-60 °C) and MGlUPRT2N (3711 IU g-1biocat; 27% retained activity; 8-20 fold enhanced stability at 50-60 °C) displayed the best operability. Moreover, the enzymatic synthesis of different pyrimidine NMPs was performed. Finally, the reusability of both derivatives in 5-FUMP synthesis (MNiUPRT23, 80% retained activity after 7 cycles, 5 min; MGlUPRT2N, 70% retained activity after 10 cycles, 20 min) was carried out at short times.

Abstract
Nowadays, pharmaceutical industry demands competitive and eco-friendly processes for active pharmaceutical ingredients (APIs) manufacturing. In this context, enzyme and whole-cell mediated processes offer an efficient, sustainable and cost-effective alternative to the traditional multi-step and environmentally-harmful chemical processes. Particularly, 2'-deoxyribosyltransferases (NDTs) have emerged as a novel synthetic alternative, not only to chemical but also to other enzyme-mediated synthetic processes. This review describes recent findings in the development and scaling up of NDTs as industrial biocatalysts, including the most relevant and recent examples of single enzymatic steps, multienzyme cascades, chemo-enzymatic approaches, and engineered biocatalysts. Finally, to reflect the inventive and innovative steps of NDT-mediated bioprocesses, a detailed analysis of recently granted patents, with specific focus on industrial synthesis of nucleoside-based APIs, is hereunder presented.

Discovery and Engineering of an Aldehyde Tolerant 2-deoxy-D-ribose 5-phosphate Aldolase (DERA) from Pectobacterium atrosepticum. Catalysts 2020.

Abstract
DERA (2-Deoxy-D-ribose 5-phosphate aldolase) is the only known aldolase that accepts two aldehyde substrates, which makes it an attractive catalyst for the synthesis of a chiral polyol motif that is present in several pharmaceuticals, such as atorvastatin and pravastatin. However, inactivation of the enzyme in the presence of aldehydes hinders its practical application. Whole cells of Pectobacterium atrosepticum were reported to exhibit good tolerance toward acetaldehyde and to afford 2-deoxyribose 5-phosphate with good yields. The DERA gene (PaDERA) was identified, and both the wild-type and a C49M mutant were heterologously expressed in Escherichia coli. The purification protocol was optimized and an initial biochemical characterization was conducted. Unlike other DERAs, which show a maximal activity between pH 4.0 and 7.5, PaDERA presented an optimum pH in the alkaline range between 8.0 and 9.0. This could warrant its use for specific syntheses in the future. PaDERA also displayed fourfold higher specific activity than DERA from E. coli (EcDERA) and displayed a promising acetaldehyde resistance outside the whole-cell environment. The C49M mutation, which was previously identified to increase acetaldehyde tolerance in EcDERA, also led to significant improvements in the acetaldehyde tolerance of PaDERA.

Abstract
2-Deoxy-D-ribose-5-phosphate aldolase (DERA) is a class I aldolase that offers access to several building blocks for organic synthesis. It catalyzes the stereoselective C-C bond formation between acetaldehyde and numerous other aldehydes. However, the practical application of DERA as a biocatalyst is limited by its poor tolerance towards industrially relevant concentrations of aldehydes, in particular acetaldehyde. Therefore, the development of proper experimental conditions, including protein engineering and/or immobilization on appropriate supports, is required. The present review is aimed to provide a brief overview of DERA, its history, and progress made in understanding the functioning of the enzyme. Furthermore, the current understanding regarding aldehyde resistance of DERA and the various optimizations carried out to modify this property are discussed.

Abstract
Nucleoside triphosphates (NTPs) are important synthetic targets with diverse applications in therapeutics and diagnostics. Enzymatic routes to NTPs from simple building blocks are attractive, however the cost and complexity of assembling the requisite mixtures of multiple enzymes hinders application. Here, we describe the use of an engineered E. coli cell-free lysate as an efficient readily-prepared multi-enzyme biocatalyst for the production of uridine triphosphate (UTP) from free ribose and nucleobase. Endogenous lysate enzymes are able to support the nucleobase ribosylation and nucleotide phosphorylation steps, while uridine phosphorylation and the production of ribose phosphates (ribose 1-phosphate, ribose 5-phosphate and phosphoribosyl pyrophosphate) require recombinant enrichment of endogenous activities. Co-expression vectors encoding all required recombinant enzymes were employed for host cell transformation, such that a cell-free lysate with all necessary activities was obtained from a single bacterial culture. ATP required as phosphorylation cofactor was recycled by endogenous lysate enzymes using cheap, readily-prepared acetyl phosphate. Surprisingly, acetyl phosphate initiated spontaneous generation of ATP in the lysate, most likely from the breakdown of endogenous pools of adenosine-containing starting materials (e.g. adenosine cofactors, ribonucleic acids). The sub-stoichiometric amount of ATP produced and recycled in this way was enough to support all ATP-dependent steps without addition of any exogenous cofactor or auxiliary enzyme. Using this approach, equimolar solutions of orotic acid and ribose are transformed near quantitatively into 1.4 g L-1 UTP within 2.5 h, using a low-cost, readily-generated biocatalytic preparation.

Abstract
Traditionally, enzymatic synthesis of nucleoside-5'-monophosphates (5'-NMPs) using low water-soluble purine bases has been described as less efficient due to their low solubility in aqueous media. The use of enzymes from extremophiles, such as thermophiles or alkaliphiles, offers the potential to increase solubilisation of these bases by employing high temperatures or alkaline pH. This study describes the cloning, expression and purification of hypoxanthine-guanine-xanthine phosphoribosyltransferase from Thermus thermophilus (TtHGXPRT). Biochemical characterization indicates TtHGXPRT as a homotetramer with excellent activity and stability across a broad range of temperatures (50-90°C) and ionic strengths (0-500mMNaCl), but it also reveals an unusually high activity and stability under alkaline conditions (pH range 8-11). In order to explore the potential of TtHGXPRT as an industrial biocatalyst, enzymatic production of several dietary 5'-NMPs, such as 5'-GMP and 5'-IMP, was carried out at high concentrations of guanine and hypoxanthine.

Abstract
Living cells are most perfect synthetic factory. The surprising synthetic efficiency of biological systems is allowed by the combination of multiple processes catalyzed by enzymes working sequentially. In this sense, biocatalysis tries to reproduce nature's synthetic strategies to perform the synthesis of different organic compounds using natural catalysts such as cells or enzymes. Nowadays, the use of multienzymatic systems in biocatalysis is becoming a habitual strategy for the synthesis of organic compounds that leads to the realization of complex synthetic schemes. By combining several steps in one pot, a significant step economy can be realized and the potential for environmentally benign synthesis is improved. Using this sustainable synthetic system, several work-up steps can be avoided and pure products are ideally isolated after a series of reactions in one single vessel after just one straightforward purification step. In recent years, enzymatic methodology for the preparation of nucleic acid derivatives (NADs) has become a standard technique for the synthesis of a wide variety of natural NADs. Enzymatic methods have been shown to be an efficient alternative for the synthesis of nucleoside and nucleotide analogs to the traditional multistep chemical methods, since chemical glycosylation reactions include several protection-deprotection steps and the use of chemical reagents and organic solvents that are expensive and environmentally harmful. In this minireview, we want to illustrate what we consider the most current relevant examples of in vivo and in vitro multienzymatic systems used for the synthesis of nucleic acid derivatives showing advantages and disadvantages of each methodology. Finally, a detailed perspective about the impact of -omics in multienzymatic systems has been described.
