Abstract
BACKGROUND Biocatalysts are a promising alternative for the production of natural flavor compounds. Candida rugosa lipase (CRL) is a particularly important biocatalyst owing to its remarkable efficiency in both hydrolysis and synthesis. However, additional stabilization is necessary for successful industrial implementation. This study presents an easy and time-saving method for immobilizing this valuable enzyme on hydroxyapatite (HAP), a biomaterial with high protein-binding capacity. RESULTS Targeted immobilized CRL was obtained in high yield of ≥98%. Significant lipase stabilization was observed upon immobilization: at 60 °C, immobilized lipase (HAP-CRL) retained almost unchanged activity after 3 h, while free CRL lost 50% of its initial activity after only 30 min. The same trend was observed with tested organic solvents. Methanol and hexane had the most pronounced effect: after 3 h, only HAP-CRL was stable and active, while CRL was completely inactivated. The practical value of the prepared catalyst was tested in the synthesis of the aroma ester methyl acetate in hexane. Reaction yields were 2.6 and 52.5% for CRL and HAP-CRL respectively. CONCLUSION This research has successfully combined an industrially prominent biocatalyst, CRL, and a biocompatible, environmentally suitable carrier, HAP, into an immobilized preparation with improved catalytic properties. The obtained CRL preparation has excellent potential for the food and flavor industries, major consumers in the global enzyme market. © 2016 Society of Chemical Industry.

Abstract
The prospect for computer-aided refinement of stereoselective enzymes is further validated by simulating the ester hydrolysis by the wild-type and mutants of CalB, focusing on the challenge of dealing with strong steric effects and entropic contributions. This was done using the empirical valence bond (EVB) method in a quantitative screening of the enantioselectivity, considering both k(cat) and k(cat)/K(M) of the R and S stereoisomers. Although the simulations require very extensive sampling for convergence they give encouraging results and major validation, indicating that our approach offers a powerful tool for computer-aided design of enantioselective enzymes. This is particularly true in cases with large changes in steric effects where alternative approaches may have difficulties in capturing the interplay between steric clashes with the reacting substrate and protein flexibility.

Abstract
The esterification of propionic acid was investigated using three different alcohols, namely, isopropyl alcohol, isobutyl alcohol, and isoamyl alcohol. The variation of conversion with time for the synthesis of isoamyl propionate was investigated in the presence of five enzymes. Novozym 435 showed the highest activity, and this was used as the enzyme for investigating the various parameters that influence the esterification reaction. The Ping-Pong Bi-Bi model with inhibition by both acid and alcohol was used to model the experimental data and determine the kinetics of the esterification reaction.

Abstract
Although lipases are known to catalyze alkoxycarbonylation reactions in organic solvents, the existing knowledge base on their substrate specificity in alkoxycarbonylation reaction is sparse. Moreover, models to predict substrate specificity have not been reported. Here, we report the experimentally measured rate constants for 180 acyl donor-alcohol pairs and demonstrate the two-step synthesis of over 70 disubstituted carbonate products from simple precursors such as diphenyl carbonate and alcohols. The efficiency of synthesis was found to be dependent on the order of alcohol addition. This motivated the need to develop a model to predict lipase specificity in alkoxycarbonylation reactions. A partial least square model has been developed to correlate the reaction rate with (i) descriptors of alcohol for a fixed acyl donor, (ii) descriptors of acyl donor for a fixed alcohol, (iii) descriptors of both the acyl donor and the alcohol. The number of descriptors being far greater than the number of observations was a potential limitation in the model development. This was addressed by selecting a subset of descriptors using a systematic procedure based on (a) correlation among the descriptors and step-wise regression methodology, and (b) variable influence on projection methodology. The model was able to accurately predict the reaction rate and the optimal order of addition of alcohols in the two-step synthesis of disubstituted carbonates using the enzyme mixture. The descriptor subset and the relevant model would benefit the users of lipases in synthetic applications while the modeling strategy presented here can have applications in predicting specificity of other enzymes.

Abstract
To investigate how the conformational flexibility of subtilisin affects its ability to discriminate between enantiomeric amino acid and ester substrates for the subtilisin-catalyzed reaction in an organic solvent, the flexibility around the active site and the surface of subtilisin was estimated from the mobility of a spin label bound to subtilisin by ESR spectroscopy. Many studies on enzyme flexibility focus on the active site. Both the surface and active site flexibility play an important role in the enantioselectivity enhancement of the enzyme-catalyzed reaction. It was found, however, that the different behavior observed for the enantioselectivity between the amino acid and ester substrates could be correlated with the flexibility around the surface rather than the flexibility at the active site of subtilisin. In other words, for the ester substrates, the greater flexibility around the surface of subtilisin induced by a conformational change resulting from the presence of an additive such as DMSO is essential for the enantioselectivity enhancement. This model is also supported by the Michaelis-Menten kinetic parameters for each enantiomeric substrate. Our findings provide insight into the enantioselectivity enhancement for the resolution of enantiomers for enzyme-catalyzed reactions in organic solvents.

Abstract
The effect of water activity (a(w)) and immobilization on fatty acid (FA) selectivity of Burkholderia (formerly Pseudomonas) cepacia, Rhizomucor miehei, Candida antarctica (type B), and Candida rugosa lipases in esterification reactions was determined. Studies were based on measuring ester formation in multicompetitive reaction mixtures containing either the homologous series of even carbon number n-chain saturated FA (C4-C18) or a series of n-chain (un)saturated FA (C18:X, where X = 0-3 double bonds) as cosubstrates with 1,3-propanediol in ter-butyl methyl ether at a(w) of 0.19, 0.69, and 0.90. Activity and FA selectively patterns were similar for free and Celite-adsorbed lipases in response to changes in a(w'), although specific effects were observed for selectivity of B. cepacia and C. rugosa lipases toward C16 and C4/C6 FA, respectively. Also, selectivity toward unsaturated C18:X FA as a group was modulated by changes in a(w) for three of the four lipase studied. Resin-fixed lipases from R. miehei and C. antarctica exhibited profound differences in activity and FA selectively in response to changes in a(w'), relative to free and Celite-bound forms. These findings suggest that FA selectivity for lipid modification is influenced by a(w) and immobilization, but that each lipase has a characteristic response to these factors in a manner that cannot be predicted.

Abstract
Various flavor esters were obtained by using recombinant lipases from Staphylococcus epidermidis as a catalyst in an aqueous environment. These esters were enzymatically synthesized to overcome the problems associated with chemical processes. This study showed that the S. epidermidis lipases could catalyze ester synthesis from decyl alcohol and fatty acids of different chain length. The wild-type and mutant lipases (M419A and V649I) could efficiently catalyze the synthesis of decyl alcohol esters of unsaturated fatty acids. In contrast, the yield of decyl laurate was better by wild-type and mutant enzyme V6491, but mutant enzyme M419A only favored the synthesis of decyl myristate. The esterification of oleic acid and various carbon-chain-length alcohols from ethanol to hexadecanol increased up to decanol by wild-type and M419A mutant enzymes and reached an optimum for dodecanol by V6491 mutant enzyme. The enzyme is potentially useful in food industries such as dairy product flavoring.

Abstract
Substituent effects on the enantioselectivity for the lipase-catalyzed esterifications in organic solvents were studied by use of 2-(4-substituted phenoxy)propionic acids as the substrates with various substituents of H, F, Cl, CF(3), CH(3), CH(3)CH(2), and CH(3)O. The distinction in the behavior of their enantioselectivity was primarily responsible for the size effects of the substituents, although the substituents are far away from the stereocenter of the substrates. For the similar substituents in size, CH(3) and CF(3), however, their electronic effects played an important role in controlling the enantioselectivity. This variation of the enantioselectivity due to the electronic effects is also supported by the discussion based on the value of the Michaelis constant (K(m)) obtained. In addition, by raising the reaction temperature with enough water added to isopropyl ether as the reaction medium, the enantioselectivity is found to be dramatically enhanced for the substrate bearing CH(3)O group due to the strong electron-donating effect.

Abstract
Fatty acid (FA) selectivity of immobilized Rhizomucor miehei lipase was determined for various cosubstrate systems for ester modification involving competing n-acyl-donor substrates of even-chain length (C4-C16; FA or their methyl esters, FAME) and either n-propanol or propyl acetate in hexane. Acyl-chain-length optima were observed for C8 and C14/16 in all cases. Upon changing between cosubstrate systems of [FA + propanol] to [FAME + propanol] to [FAME + propyl acetate], there was a general shift in selectivity toward shorter-chain-length FA (C4-C8). The greatest degree of reaction selectivity (based on ratios of selectivity constants) among the FA substrates was 3.1 for the [FA + propanol], 2.5 for the [FAME + propanol], and 1.4 for the [FAME + propyl acetate] cosubstrate systems. For esterification reactions between C6 FA and reactive members of a series of aliphatic and aromatic alcohols, the greatest degree of selectivity observed was 3.6.

Abstract
Kinetic resolution of racemic compounds by enzymatic hydrolysis with non-enantioselective separation of enantiomer products via a separator or ion-pair formation has been quantitatively analyzed. Theoretical results indicate that the removal of chiral products has profound effects on improving the conversion and enantiomeric excess for the desired chiral substrate or product. The analysis was confirmed from lipase-catalyzed hydrolysis of racemic methyl 2-chloropropionate in the presence of pyrrolidine in buffer saturated dichloromethane.

Abstract
The equilibrium position in lipase mediated esterification of various fatty acids and butanol was studied. The influence of the chain length and the presence of unsaturations in the fatty acids on the equilibrium position was measured and predicted. To predict equilibrium position the program TREP extended (TREPEX) based on the UNIFAC group contribution method was used. Using an equilibrium constant of 35, calculated on the basis of thermodynamic activities, the equilibrium position between butanol and saturated and/or unsaturated fatty acids with different chain lengths can be predicted. The ester mole fraction at equilibrium increases with the fatty acid chain length, and for fatty acids with the same carbon number, the highest values are found for unsaturated fatty acids. For reaction systems containing two saturated fatty acids, a slightly higher mole fraction is obtained for the fatty acid with the higher chain length, while for mixtures consisting of saturated and unsaturated fatty acids, the mole fractions of the unsaturated esters are lower than those of the saturated ones, regardless the chain length of the fatty acid. These experimental results are in good agreement with the calculations with TREPEX.

Abstract
Lipid acyl hydrolase (LAH; patatin) was purified from potato tubers by ammonium sulfate fractionation followed by anion-exchange and affinity chromatography. The major protein band of 40-43 kDa on SDS-PAGE appeared to be patatin, and it stained positive for lipase activity on native PAGE. Selectivity of a Celite-immobilized potato LAH in esterification reactions with n-acyl fatty acids (FA; C4, C6, C8, C10, C12, C14, C16, and C18) and alcohol acceptors (n-propanol, 2-propanol, 1,3-propanediol, and glycerol; 1,2-propanediol was not sufficiently reactive) was studied in isooctane. Immobilized LAH was highly selective for medium chain FAs (C8/C10) with a secondary optimum for chain lengths of C14/16. Water activity (a(w)) influenced activity and FA selectivity of the enzyme. Initial rates of ester synthesis were greatest at a(w) of 0.90 for all alcohol acceptors except for glycerol, where greatest initial rates were observed at a(w) of 0.19. Immobilized LAH preparations exhibited a bell-shape pH profile with optimum activity at pH 6-7 for ester synthesis, and no effect of pH on FA selectivity was observed.

Abstract
The enantioselective recognition mechanism of secondary alcohol by lipases originated from Candida rugosa and Pseudomonas cepacia was elucidated on the basis of the kinetic study of the esterification of alcohol with lauric acid in isooctane. To obtain inherent kinetic parameters, we utilized a surfactant-coated lipase whose conformation is considered to be an "open" form in a homogeneous organic solvent. Based on the experimental results, the enantioselectivity of lipases was found to be derived from the difference in the V(max) values between the two enantiomers. The same result was observed when lipases of different origin and substrates with different molecular structures were applied. © 1999 John Wiley & Sons, Inc.

Abstract
Alcohol inhibition of the lipase B from Candida antarctica has been studied through two different approaches: using the same inhibitor (1-butanol) in different organic solvents and using different inhibitors (differing in chain length) in the same solvent. The competitive inhibition constant values obtained in each case correlate with the calculated activity coefficients of the substrate, suggesting that desolvation of the alcohol is the major force changed. Data dispersion observed using the second approach has been interpreted to come from contributions of enzyme-inhibitor interactions to the binding energy. On the other hand, deacylation has been found to be much less influenced by the solvent variation than the acylation step, despite of the fact that solvation of the substrate involved in this step (the alcohol) is expected to change more than for the ester. Concerning the specificity behavior of the enzyme, a bimodal pattern was observed for the deacylation rate dependence on the alcohol chain length, with the highest values for hexanol (C6) and decanol (C10). With regard to the ester specificity, ethyl caproate (C6) is the preferred one. These results have been confronted with those reported for the lipase from Candida rugosa.
