Abstract
Esterases are important biocatalysts for chemical synthesis. Several bHSL family esterases have been used to prepare (S)-2-arylpropionic acids with stronger anti-inflammatory effects via kinetic resolution. Here, we presented the discovery of key residues that controlled the enantioselectivity of bHSL family esterases to ethyl 2-arylpropionates, through careful analysis of the structural information and molecular docking. A new bHSL family esterase, Est924, was identified as a promising catalyst for kinetic resolution of racemic ethyl 2-arylpropionates with slight (R)-stereopreference. Using Est924 as the starting enzyme, protein engineering was conducted at hotspots, and the substitution of A203 was proved to enhance the enantioselectivity. The stereopreference of the mutant M1 (A203W) was inverted to ethyl (S)-2-arylpropionates, and this stereopreference was further improved in variant M3 (I202F/A203W/G208F). In addition, the optimal variant, M3, was also suitable for the resolution of ibuprofen ethyl ester and ketoprofen ethyl ester, and their efficient (S)-isomers were synthesized. Next, the whole-cell catalyst harboring M3 was used to prepare (S)-ketoprofen. (S)-ketoprofen with 86%ee was produced by whole-cell catalyst with a single freeze-thaw cycle, and the cells could be reused for at least five cycles. Our results suggested that Est924 variants could kinetically resolve economically important racemates for industrial production and further offer the opportunity for the rational design of enzyme enantioselectivity. Moreover, it is an economical process to prepare optically pure (S)-ketoprofen and (S)-naproxen by using an engineered strain harboring M3 as the catalyst.

Abstract
This review presents the most relevant investigations concerning the biocatalytic kinetic resolution of racemic ketoprofen to dexketoprofen for the last 22 years. The advantages related to the administration of the dex-enantiomer in terms of human health, the so called "chiral switch" in the pharmaceutical industry and the sustainability of biotransformations have been the driving forces to develop innovative technology to obtain dexketoprofen. In particular, the kinetic resolution of racemic ketoprofen through enantiomeric esterification and hydrolysis using lipases as biocatalysts are thoroughly revised and commented upon. In this context, the biocatalysts, acyl-acceptors (alcohols), reaction conditions, conversion, enantiomeric excess, and enantiomeric ratio among others are discussed. Moreover, the investigations concerning scaling up processes in order to obtain an optically pure enantiomer of the profen are presented. Finally, some guidelines about perspectives of the technology and research opportunities are given.

Abstract
The bacterium KS-1, capable of degrading fluoroglycofen, was isolated from sludge collected at a herbicide factory. The isolate was identified as Lysinibacillus sp. according to its phenotypic features and 16S rDNA phylogeny. KS-1 degraded 85.25% of the fluoroglycofen (50 mg L-1) within 3 days of incubation. The optimum temperature and pH for fluoroglycofen degradation were 30°C and 7.0, respectively. Furthermore, Zn2+ and Cu2+ could significantly decrease the degradation rate. Three degradation products, which appeared during KS-1-mediated fluoroglycofen metabolism, were identified as deethyl-fluoroglycofen, acifluorfen and decarboxylate-acifluorfen. The fluE gene, which encodes a novel esterase that catalyzes the cleavage of carboxyl ester bonds of fluoroglycofen, was cloned from the KS-1 strain. Sequence alignment reveals that FluE shares 30%-40% amino acid sequence identity with members of the hormone sensitive lipase family. FluE was expressed in Escherichia coli BL21 and purified by Ni-NTA affinity chromatography. Purified FluE could efficiently hydrolyze fluoroglycofen and short-chain p-nitrophenol esters. However, no lipolytic activity was observed with esters containing acyl chains longer than 10 carbon atoms, thereby indicating that this enzyme is an esterase.

Abstract
An esterase PE10 (279 aa) from Pelagibacterium halotolerans B2(T) was cloned and overexpressed in Escherichia coli Rosetta in a soluble form. The deduced protein was 29.91 kDa and the phylogenetic analysis of the deduced amino acids sequence showed it represented a new family of lipolytic enzymes. The recombinant protein was purified by Ni-NTA affinity chromatography column and the characterization showed its optimal temperature and pH were 45 °C and pH 7.5, respectively. Substrate specificity study showed PE10 preferred short chain p-nitrophenyl esters and exhibited maximum activity toward p-nitrophenyl acetate. In addition, PE10 was a halotolerant esterase as it was still active under 4 M NaCl. Three-dimensional modeling of PE10 suggested that the high negative electrostatic potential on the surface may relevant to its tolerance to high salt environment. With this halotolerance property, PE10 could be a candidate for industrial use.

Abstract
Bicontinuous microemulsion was employed as the medium for enzymatic hydrolysis of (R,S)-ketoprofen ethyl ester in the presence of esterase for the first time. In addition, a methodology for the separation of optically pure ketoprofen from the microemulsion system for analysis by gas chromatography was developed. Various factors influencing the enzymatic hydrolysis of (R,S)-ketoprofen ethyl ester such as temperature, enzyme concentration and reaction time were optimized experimentally. The enzymatic hydrolysis in a bicontinuous microemulsion system showed a final conversion of 84.6% after 50 h of reaction, while hydrolysis in Tris-HCl buffer solution resulted in only 26.9% conversion after 150 h without completing the reaction. A comparison of the rate of the enzymatic hydrolysis reaction with rates of reaction in other biphasic media revealed that the bicontinuous microemulsion system was faster and more advantageous. The extremely large interfacial area of the latter fluid likely facilitated the contact between the catalyst and the substrate. Because the enzyme applied was not selective, formation of (R)-ketoprofen was also observed. Therefore, application of an enzyme with higher selectivity would provide better results.

Abstract
The gene GK3045 (741 bp) from Geobacillus kaustophilus HTA426 was cloned, sequenced, and overexpressed into Escherichia coli Rosetta (DE3). The deduced protein was a 30-kDa monomeric esterase with high homology to carboxylesterases from Geobacillus thermoleovorans NY (99% identity) and Geobacillus stearothermophilus (97% identity). This protein suffered a proteolytic cut in E. coli, and the problem was overcome by introducing a mutation in the gene (K212R) without affecting the activity. The resulting Est30 showed remarkable thermostability at 65 degrees C, above the optimum growth temperature of G. kaustophilus HTA426. The optimum pH of the enzyme was 8.0. In addition, the purified enzyme exhibited stability against denaturing agents, like organic solvents, detergents, and urea. The protein catalyzed the hydrolysis of p-nitrophenyl esters of different acyl chain lengths, confirming the esterase activity. The sequence analysis showed that the protein contains a catalytic triad formed by Ser93, Asp192, and His222, and the Ser of the active site is located in the conserved motif Gly91-X-Ser93-X-Gly95 included in most esterases and lipases. However, this carboxylesterase showed no more than 17% sequence identity with the closest members in the eight families of microbial carboxylesterases. The three-dimensional structure was modeled by sequence alignment and compared with others carboxylesterases. The topological differences suggested the classification of this enzyme and other Geobacillus-related carboxylesterases in a new alpha/beta hydrolase family different from IV and VI.

Abstract
A newly isolated gene from Ralstonia sp. M1, encoding an esterase, was cloned in Escherichia coli and its nucleotide sequence determined. The 1.6kb insert revealed one complete open reading frame, predicted to encode an esterase (320 aa, 34.1kDa) with a pI of 9.86. EstR contained a putative oxyanion hole H36G37, a conserved pentapeptide G103HSLG107 and a conserved catalytic His265 and Asp237. The EstR sequence shared 64-70 and 44-48% identity with the hydrolases/acyltransferases from Burkholderia strains and from Ralstonia strains, respectively, 44 and 38% identity with the lactone-specific esterase from Pseudomonas fluorescens and Mesorhizobium loti, respectively. The esterase EstR was expressed with a high level of 41mg/g wet cells. The Ni-NTA-purified esterase EstR showed an optimal activity in the temperature range 60-65 degrees C and pH range 7.5-9.0 towards p-nitrophenyl caproate. The enzyme was found to be highly resistant to many organic solvents especially induced by ethanolamine. Metal ions showed slight effect on esterase activity. The inhibitor phenylmethanesulfonyl fluoride inhibited strongly the esterase. Triton X-45 induced the activation of EstR, but other detergents slightly to strongly decreased or completely inhibited. Among tested p-NP esters, caproate was the most preferential substrate of this esterase.
