Abstract
Cross-linked enzyme crystal (CLEC) and sol-gel entrapped pseudomonas sp. lipase were investigated for the esterification of lauric acid with ethanol by considering the effects of reaction conditions on reaction rate. The activation energy for the reaction was estimated to be 1097.58 J/mol and 181.75 J/mol for sol-gel and CLEC entrapped lipase respectively. CLEC lipase exhibited a marginal internal diffusion effect on reaction rate over sol-gel lipases and found to be interesting. The overall reaction mechanism was found to conform to the Ping Pong Bi Bi mechanism. The higher efficiency of sol-gel lipases over CLEC lipases in esterification reaction is mainly due to the combined effects of crowding, confinement and diffusional limitations.

Abstract
Lipases (EC 3.1.1.3) are ubiquitous hydrolases for the carboxyl ester bond of water-insoluble substrates, such as triacylglycerols, phospholipids, and other insoluble substrates, acting in aqueous as well as in low-water media, thus being of considerable physiological significance with high interest also for their industrial applications. The hydrolysis reaction follows a two-step mechanism, or “interfacial activation,” with adsorption of the enzyme to a heterogeneous interface and subsequent enhancement of the lipolytic activity. Among lipases, Candida antarctica lipase B (CALB) has never shown any significant interfacial activation, and a closed conformation of CALB has never been reported, leading to the conclusion that its behavior was due to the absence of a lid regulating the access to the active site. The lid open and closed conformations and their protonation states are observed in the crystal structure of CALB at 0.91 Å resolution. Having the open and closed states at atomic resolution allows relating protonation to the conformation, indicating the role of Asp145 and Lys290 in the conformation alteration. The findings explain the lack of interfacial activation of CALB and offer new elements to elucidate this mechanism, with the consequent implications for the catalytic properties and classification of lipases.

Abstract
One important parameter for the application of lipase catalysts in chemical industries is the specific activity displayed towards natural or unnatural substrates. Different strategies to enhance the lipase activity have been described. The immobilization of lipases on hydrophobic supports by interfacial adsorption at low ionic strength permitted the hyper-activation of these enzymes by fixing the open conformation of the lipase on the hydrophobic support. Improvements of activity from 1.2- up to 20-fold with respect to the initial one have been observed for lipases from different sources. A second strategy was based on the presence of additives, in particular surfactants or ionic liquids, with hydrophobic character to enhance the activity of lipases immobilized on macroporous supports up to eightfold and even more than 100-fold in some cases for soluble lipases. Finally, a third strategy to improve the activity in immobilized lipases was based on a site-directed chemical modification of the protein by glycosylation on the enzyme N-terminal group or on a unique reactive cysteine of the enzyme by disulfide exchange using different tailor-made disulfide activated activated polymers.

Abstract
In this work, lipase from Arthrobacter sp. was immobilized by sol-gel encapsulation to improve its catalytic properties. Various silanizing agents including vinyl-trimethoxy silane, octyl-trimethoxy silane, gamma-(methacryloxypropyl)-trimethoxy silane (MAPTMS) and tetraethoxysilane (TEOS) were chosen as the precursors. Among them, MAPTMS was for the first time utilized to encapsulate lipases, and the prepared enzyme by copolymerization of MAPTMS and TEOS exhibited the highest activity in both the hydrolysis of p-nitrophenyl palmitate and the asymmetric acylation of 4-hydroxy-3-methyl-2-(2-propenyl)-2-cyclopenten-1-one. The effects of various immobilization parameters were investigated. Under the optimum conditions of MAPTMS/TEOS=1/1 (mol/mol), water/silane molar ratio (R value)=20 and lipase loading=0.01 g/mL sol, the total activity of the immobilized enzyme reached up to 13.6-fold of the free form. Moreover, the encapsulated lipase exhibited higher thermal stability than the free form and retained 54% of the original activity after uses for 60 d. Enantioselectivity of enzyme was also improved with an E value of 150 after encapsulation from 85 for the free form.

Abstract
We have synthesized a novel interface-anchoring alcohol dehydrogenase by covalent attachment of a hydrophobic polymer tail to the hydrophilic protein head. Analogous to a protein-based surfactant, this polymer-enzyme conjugate self-assembled at liquid-liquid or liquid-air interfaces to form a membrane similar to other surfactant monolayers. The packing and morphology of the interface-anchored enzymes play an important role in regulating the membrane behaviors including enzyme mobility and interfacial interactions of enzymes with reactant and product molecules. To characterize the surface assembly morphology of the interface-anchored enzymes, Langmuir film balance and fluorescence microscopy techniques were used. The Langmuir isotherm of the interface-anchored enzyme demonstrated a pronounced molecular rearrangement upon compression of the isotherm. This corresponded to changes in membrane morphology and state observed using fluorescence microscopy. The molecular diffusion within the novel interface-anchored enzymes was further evaluated by using a fluorescence recovery after photobleaching technique. We report a diffusion coefficient of 6.7x10(-10) cm2/s. The study represents the first in-depth analysis of surface packing and interfacial mobility of such interface-anchored enzymes.

Abstract
Microbial lipases are very prominent biocatalysts because of their ability to catalyze a wide variety of reactions in aqueous and non-aqueous media. The chemo-, regio- and enantio-specific behaviour of these enzymes has caused tremendous interest among scientists and industrialists. Lipases from a large number of bacterial, fungal and a few plant and animal sources have been purified to homogeneity. This article presents a critical review of different strategies which have been employed for the detection, purification and characterization of microbial lipases.

Abstract
In recent times, biotechnological applications of microbial lipases in synthesis of many organic molecules have rapidly increased in non-aqueous media. Microbial lipases are the 'working horses' in biocatalysis and have been extensively studied when their exceptionally high stability in non-aqueous media has been discovered. Stability of lipases in organic solvents makes them commercially feasibile in the enzymatic esterification reactions. Their stability is affected by temperature, reaction medium, water concentration and by the biocatalyst's preparation. An optimization process for ester synthesis from pilot scale to industrial scale in the reaction medium is discussed. The water released during the esterification process can be controlled over a wide range and has a profound effect on the activity of the lipases. Approaches to lipase catalysis like protein engineering, directed evolution and metagenome approach were studied. This review reports the recent development in the field ofnon-aqueous microbial lipase catalysis and factors controlling the esterification/transesterification processes in organic media.

Abstract
Cytochrome P450 monooxygenases (P450s) are powerful biocatalysts that have the ability to oxidize a broad range of substrates, often at non-reactive carbon centers. However, incorporation of P450s into synthetic schemes has so far been limited to a few whole-cell transformations. P450 substrates are often hydrophobic and have low water solubility, limiting the amount of product that can be produced. To help overcome this limitation, we have examined P450cam activity in two-phase hexane/water emulsions with and without the anionic surfactant, bis(2-ethylhexyl) sulfosuccinate sodium salt (AOT). Hydroxylation of camphor to hydroxycamphor by the three- component P450cam system was chosen as the model reaction, and regeneration of NADH was accomplished with yeast alcohol dehydrogenase (YADH). P450cam was activated in the surfactant-free emulsions, and addition of AOT improved the activity even further, at least over the range of camphor concentrations for which initial rates were readily measurable in all media. The largest observed rate enhancement was 4.5-fold. Nearly 50-times more product was formed in the surfactant-stabilized emulsions than was achieved in aqueous buffer, with total turnover numbers reaching 28,900 for P450cam and 11,800 for YADH. In the absence of surfactant, the two-phase reaction appeared to be mass-transfer limited, while inclusion of AOT alleviated transport limitations and/or afforded a larger interfacial area for P450 activation. The oxidation of hydroxycamphor to 2,5-diketocamphane was also observed, owing to the large concentration of hydroxycamphor relative to camphor in the aqueous phase of the two-phase emulsion. This competing reaction was accompanied by the uncoupled oxidation of NADH (i.e., NADH oxidation without formation of 2,5-diketocamphane), which reduced the availability of NADH for camphor oxidation and further limited the yield of hydroxycamphor in the two-phase emulsions. These results indicate that a surfactant-stabilized two-phase emulsion is a promising reaction medium for practical P450 biocatalysis, although its effectiveness for a given P450/substrate combination can depend on several factors, including competitive or sequential reactions, product inhibition, and NAD(P)H uncoupling.

Abstract
The addition of a very small concentration of a detergent (in many instances under the critical micellar concentration (cmc)) has been found to greatly increase the activity of immobilized lipases, using those from Pseudomonas fluorescens (PFL) and Candida antarctica (isoform B) as model enzymes. However, the detergents may also have a negative effect on enzyme activity; in fact, for all enzyme preparations and substrates the activity/detergent concentration curve reached a maximum value and started to decrease, in many instances even under the initial value. The concentration and nature of the detergent (SDS, CTAB, Triton X-100, or X-45) that permitted the maximum hyperactivation was different depending on the substrate. The best hyperactivation values promoted by the presence of detergent were over a 20-fold factor. The presence of detergents permitted the inhibition of lipases by irreversible covalent inhibitors (e.g., 4-(2-aminoethyl)benzenesulfonyl fluoride hydrochloride) (AEBSF) while the enzyme, in the absence of detergent, is not inhibited by these irreversible inhibitors. This suggested that the main effect of the detergents is to shift the conformational equilibrium of lipases toward the open form. Moreover, the presence of detergents also permitted to improve the enantioselectivity exhibited by the immobilized lipases in some cases. For example, the enantioselectivity of PFL-glyoxyl agarose increased from 40 to more than 100 in the hydrolysis of (+/-)-2-hydroxy-4-phenylbutyric acid ethyl ester by using 0.1% CTAB.

Abstract
Lipases from Candida rugosa (CRL) and lipase isoforms A and B from Candida antarctica (CAL-A and CAL-B) were adsorbed on aminated supports in the presence of detergents to have individual lipase molecules. Then, one fraction was washed to eliminate the detergent, and both preparations were treated with glutaraldehyde. The presence of detergent during the cross-linking of the lipases to the support permitted an increase in the recovered activity (in some instances, even by a 10-fold factor). This activity was higher even than that exhibited by the just adsorbed lipases, suggesting that it was not a result of some protective effect of the detergent in the enzyme activity during glutaraldehyde chemical modification. Moreover, the enantioselectivity of the different enzyme preparations was very different if the glutaraldehyde was offered in the presence or in the absence of detergent, in some cases increasing the E value (even by a 7-fold factor in the case of CAL-A in the hydrolysis of (+/-)-2-hydroxy-4-phenylbutyric acid ethyl ester), in other cases even inverting the enantio preference (e.g., in the case of CRL). The irreversible chemical inhibition of the enzyme that was immobilized and cross-linked with glutaraldehyde in the presence of detergents was more rapid than that in the other preparations (by more than a 10-fold factor). This experiment reveals an exposition degree of the active serine in the preparation cross-linked with the support in the presence of detergent that is higher than that in the other preparations. The results suggested that different enzyme structures were "stabilized" by the glutaraldehyde treatment if performed in the presence or in the absence of detergent, and that, in the presence of detergent, a form of the lipase with the serine residue more exposed to the medium and much more active could be obtained. This strategy seems to be of general use to improve the lipase activity to be used in macroaqueous media.

Abstract
Candida antarctica lipase B (CALB) and Thermomyces lanuginosa lipase (TLL) were evaluated as catalysts in different reaction media using hydrolysis of tributyrin as model reaction. In o/w emulsions, the enzymes were used in the free form and for use in monophasic organic media, the lipases were adsorbed on porous polypropylene (Accurel EP-100). In monophasic organic media, the highest specific activity of both lipases was obtained in pure tributyrin at a water activity of >0.5 and at an enzyme loading of 10 mg/g support. With tributyrin emulsified in water, the specific activities were 2780 micromol min(-1) mg(-1) for TLL and 535 micromol min(-1) mg(-1) for CALB. Under optimal conditions in pure tributyrin, CALB expressed 49% of the activity in emulsion (264 micromol min(-1) mg(-1)) while TLL expressed only 9.2% (256 micromol min(-1) mg(-1)) of its activity in emulsion. This large decrease is probably due to the structure of TLL, which is a typical lipase with a large lid domain. Conversion between open and closed conformers of TLL involves large internal movements and catalysis probably requires more protein mobility in TLL than in CALB, which does not have a typical lid region. Furthermore, TLL lost more activity than CALB when the water activity was reduced below 0.5, which could be due to further reduction in protein mobility.

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
Lipases contained in commercial samples of lipase extracts from Rhizopus niveus (RNL) and Candida rugosa (CRL) have been selectively adsorbed on hydrophobic supports at very low ionic strength. Under these conditions, adsorption of other proteins (including some esterases) is almost negligible. More interestingly, these lipases could be separated in several active fractions as a function of a different rate or a different intensity of adsorption on supports activated with different hydrophobic groups (butyl-, phenyl- and octyl-agarose). Thus, although RNL seemed to be a homogeneous sample by SDS-PAGE, it could be separated, via sequential adsorption on the different supports, into three different fractions with very different thermal stability and substrate specificity. For example, one fraction hydrolyzed more rapidly ethyl acetate than ethyl butyrate, while another hydrolyzed the acetate ester 7-fold slower than the butyrate. Similar results were obtained with samples of CRL. Again, we could obtain three different fractions showing very different properties. For example, enantioselectivity for the hydrolysis of (R,S) 2-hydroxy-4-phenylbutanoic acid ethyl ester ranged from 1.2 to 12 for different CRL fractions. It seems that very slight structural differences may promote a quite different interfacial adsorption of lipases on hydrophobic supports as well as a quite different catalytic behavior. In this way, this new 'interfacial affinity chromatography' seems to be very suitable for an easy separation of such slightly different lipase forms.

Abstract
A number of bacterial lipases can be immobilized in a rapid and strong fashion on octyl-agarose gels (e.g., lipases from Candida antarctica, Pseudomonas fluorescens, Rhizomucor miehei, Humicola lanuginosa, Mucor javanicus, and Rhizopus niveus). Adsorption rates in absence of ammonium sulfate are higher than in its presence, opposite to the observation for typical hydrophobic adsorption of proteins. At 10 mM phosphate, adsorption of lipases is fairly selective allowing enzyme purification associated with their reversible immobilization. Interestingly, these immobilized lipase molecules show a dramatic hyperactivation. For example, lipases from R. niveus, M. miehei, and H. lanuginosa were 6-, 7-, and 20-fold more active than the corresponding soluble enzymes when catalyzing the hydrolysis of a fully soluble substrate (0.4 mM p-nitrophenyl propionate). Even higher hyperactivations and interesting changes in stereospecificity were also observed for the hydrolysis of larger soluble chiral esters (e.g. (R,S)-2-hydroxy-4-phenylbutanoic ethyl ester). These results suggest that lipases recognize these "well-defined" hydrophobic supports as solid interfaces and they become adsorbed through the external areas of the large hydrophobic active centers of their "open and hyperactivated structure". This selective interfacial adsorption of lipases becomes a very promising immobilization method with general application for most lipases. Through this method, we are able to combine, via a single and easily performed adsorption step, the purification, the strong immobilization, and a dramatic hyperactivation of lipases acting in the absence of additional interfaces, (e.g., in aqueous medium with soluble substrate).
