Abstract
(R)-N-(2,6-dimethylphenyl) aminopropionic acid methyl ester ((R)-DMPM) is an important chiral intermediate of the fungicide N-(2,6-Dimethylphenyl)-N-(methoxyacetyl)-alanine methyl ester ((R)-Metalaxyl). In this study, (1) D3520 (macroporous acrylic anion resin), selected from the ten resins, was used to immobilize the esterase from Pseudochrobactrum asaccharolyticum WZZ003 (PAE07) for resoluting the (R,S)-DMPM to obtain (R)-DMPM. (2) Up to 20 g/L PAE07 could be immobilized onto D3520 with a high enzymatic activity of 32.4 U/g. Moreover, the Km and Vmax values of 19.1 mM and 2.8 mM/min for D3520-immobilized PAE07 indicated its high activity and stereoselectivity. (3) The optimal temperature and pH for the immobilized PAE07 were 40 ℃ and 8.0, and substrate concentration was up to 0.35 M. After 15 h reaction, the conversion rate from (R,S)-DMPM to (R)-DMPM was 48.0% and the e.e.p and E values were 99.5% and 1393.0, respectively. In scale-up resolution, 200 g/L substrate and 12.5 g immobilized esterase PAE07 condition, a conversion rate from substrate to product of 48.1% and a product e.e.p of 98% were obtained within 12 h, with the activity of immobilized PAE07 retained 80.2% after 5 cycles of reactions. These results indicated that the D3520-immobilized esterase PAE07 had great potential for enzymatic resolution of (R,S)-DMPM to prepare (R)-Metalaxyl.

Abstract
Chiral α-aryl glycines play a key role in the preparation of some bioactive products, however, their catalytic asymmetric synthesis is far from being satisfactory. Herein, we report an efficient nickel-catalyzed asymmetric hydrogenation of N-aryl imino esters, affording chiral α-aryl glycines in high yields and enantioselectivities (up to 98% ee). The hydrogenation can be conducted on a gram scale with a substrate/catalyst ratio of up to 2000. The obtained chiral N-p-methoxyphenyl α-aryl glycine derivatives are not only directly useful chiral secondary amino acid esters but can also be easily deprotected by treatment with cerium ammonium nitrate for further transformations to several widely used molecules including drug intermediates and chiral ligands. Formation of a chiral Ni-H species in hydrogenation is detected by 1H NMR. Computational results indicate that the stereo selection is determined during the approach of the substrate to the catalyst. Chiral α-amino acids find application in the fields of pharmaceutical, biological and synthetic chemistry. Here, the authors report a nickel-catalyzed asymmetric hydrogenation of N-aryl imino esters affording chiral α-aryl glycines in high yields and enantioselectivities.

Abstract
The gene encoding carboxylesterase from the hyperthermophilic bacterium Thermotoga maritima (tm0053) was cloned. The recombinant protein (EST53) was overexpressed in Escherichia coli without its NH(2)-terminal hydrophobic region, and with a C-terminal hexahistidine sequence. The enzyme was purified to homogeneity by heat treatment, followed by Ni(2+) affinity chromatography, and then characterized. Among the p-nitrophenyl esters tested, the best substrate was p-nitrophenyl decanoate with K (m) and k (cat) values of 3.1 muM and 10.8 s(-1), respectively, at 60 degrees C and pH 7.5. The addition of O,O'-bis(2-aminoethyl)ethyleneglycol-N,N,N',N'-tetraacetic acid decreased the esterase activity, indicating that EST53 is dependent on the presence of Ca(2+) ion. In addition, its activity was inhibited by the addition of phenylmethylsulfonyl fluoride and diethyl pyrocarbonate, indicating that it contains serine and histidine residues, which play key roles in the catalytic mechanism. EST53 shows a relatively high degree of similarity to Burkholderia lipases that belong to family I.2 of the lipolytic enzymes, whereas the local sequence around the pentapeptide of EST53 is most similar to those of Bacillus lipases belonging to family I.4.
