Abstract
Enzymes are highly efficient and selective biocatalysts, present in the living beings. They exist in enormous varieties in terms of the types of reactions catalyzed by them for instance oxidation-reduction, group transfers within the molecules or between the molecules, hydrolysis, isomerization, ligation, bond cleavage, and bond formation. Besides, enzyme based catalyses are performed with much higher fidelity, under mild reaction conditions and are highly efficient in terms of number of steps, giving them an edge over their chemical counter parts. The unique characteristics of enzymes makes them highly applicable fora number of chemical transformation reactions in pharmaceutical industries, such as group protection and deprotection, selective acylation and deacylation, selective hydrolysis, deracemization, kinetic resolution of racemic mixtures, esterification, transesterification, and many others. In this review, an overview of the enzymes, their production and their applications in pharmaceutical syntheses and enzyme therapies are presented with diagrams, reaction schemes and table for easy understanding of the readers.

Abstract
Propargylamines are a versatile class of compounds which find broad application in many fields of chemistry. This review aims to describe the different strategies developed so far for the synthesis of propargylamines and their derivatives as well as to highlight their reactivity and use as building blocks in the synthesis of chemically relevant organic compounds. In the first part of the review, the different synthetic approaches to synthesize propargylamines, such as A3 couplings and C-H functionalization of alkynes, have been described and organized on the basis of the catalysts employed in the syntheses. Both racemic and enantioselective approaches have been reported. In the second part, an overview of the transformations of propargylamines into heterocyclic compounds such as pyrroles, pyridines, thiazoles, and oxazoles, as well as other relevant organic derivatives, is presented.

Abstract
Abstract
For the production of enantiopure β-amino acids, enantioselective resolution of N-acyl β-amino acids using acylases, especially those recognizing N-acetyl-β-amino acids, is one of the most attractive methods. Burkholderia sp. AJ110349 had been reported to exhibit either (R)- or (S)-enantiomer selective N-acetyl-β-Phe amidohydrolyzing activity, and in this study, both (R)- and (S)-enantioselective N-acetyl-β-Phe acylases were purified to be electrophoretically pure and determined the sequences, respectively. They were quite different in terms of enantioselectivities and in their amino acids sequences and molecular weights. Although both the purified acylases were confirmed to catalyze N-acetyl hydrolyzing activities, neither of them show sequence similarities to the N-acetyl-α-amino acid acylases reported thus far. Both (R)- and (S)-enantioselective N-acetyl-β-Phe acylase were expressed in Escherichia coli. Using these recombinant strains, enantiomerically pure (R)-β-Phe (>99% ee) and (S)-β-Phe (>99% ee) were obtained from the racemic substrate.

Abstract
This organic laboratory experiment introduces students to stereoselective enzyme reactions, resolution of enantiomers, and NMR analysis of diastereomers. The reaction between racemic 1-phenylethanol and vinyl acetate in hexane to form an ester is catalyzed by acylase I. The unreacted alcohol is then treated with a chiral acid and the resulting ester diastereomer is analyzed by NMR. This experiment is suitable for group work in the laboratory as several diastereomers are synthesized and compared to determine which enantiomer of 1-phenylethanol reacts with the enzyme.

Abstract
A study of various direct condensations between different amines, having very high pK values, and unmodified acyl donors has been performed. This has been possible by the use of a very stable PGA derivative. First, it has been found that the higher the cosolvent concentration, the higher the pK of the acyl donor and thus the higher the yield. Therefore, these high concentrations of cosolvents seem to be a requisite for certain enzymatic condensations. Using ethanolamine and 2-hydroxy-2-phenylethyl-amine as nucleophiles and phenyl acetic acid as the acyl donor, the increase in the diglyme concentration from 50 to 90% (v/v) permitted improvement of not only the yield (reaching values higher than 99% in both cases) but also the reaction rates (by 360- or 3-fold, respectively). However, even when using PGA preparations stabilized by multipoint covalent attachment, it was not possible to obtain these results by inactivation of the enzyme derivative. Thus, in the protection of the octylamine with phenylacetic acid in 90% diglyme, the enzymatic activity was more than 20-fold higher using the hydrophilized derivative than the glyoxyl PGA, which allowed us to obtain a yield higher than 99%. Thus, the use of hydrophilized derivatives that are very stable even in the presence of high concentrations of organic solvents opens new opportunities in the use of PGA in organic chemistry.

Abstract
Cheese whey (CW) is the major subproduct from cheese manufacturing and it is considered as a waste pollutant since its high content of lactose. In this work a fermentation process for the production of penicillin acylase (PA) by a recombinant Escherichia coli and using CW as unique carbon source and inducer was developed. A design factorial 3(2) was used to evaluate the influence of independent variables (dissolved oxygen and CW concentration) on the ability of E. coli W3110/pPA102 to produce PA. Maximum specific PA activity of 781 U g(-1) was attained at 5 g L(-1) of CW and 3% dissolved oxygen. The results showed that CW can be used successfully as unique carbon source and inducer for the production of recombinant proteins using constructions driven by the lac promoter and this way reducing the discharges of that pollutant to the environment.

Abstract
In this work, we have used supports activated with m-amino-phenylboronic groups to "reversibly" immobilize proteins under very mild conditions. Most of the proteins contained in a crude extract from E. coli could be immobilized on Eupergit C-250 L activated with phenylboronic and then fully desorbed from the support by using mannitol or SDS. This suggested that the immobilization of the proteins on these supports was not only via sugars interaction, but also by other interaction/s, quite unspecific, that might be playing a key role in the immobilization of the proteins. Penicillin acylase from E. coli (PGA) was also immobilized in Eupergit C activated with m-amino-phenylboronic groups. The enzyme could be fully desorbed with mannitol immediately after being immobilized on the support. However, longer incubation times of the immobilized preparation caused a reduction of protein elution from the boronate support in presence of mannitol. Moreover, these immobilized preparations showed a higher stability in the presence of organic solvents than the soluble enzyme; the stability also improved when the incubation time was increased (to a factor of 100). By desorbing the weakest bound enzyme molecules, it was possible to correlate adsorption strength with stabilization; therefore, it seems that this effect was due to the rigidification of the enzyme via multipoint attachment on the support.

Abstract
[reaction: see text] A practical, large-scale synthesis of a beta-amino ester 1 was developed. A chiral imine derived from (S)-phenylglycinol and 3-trimethylsilylpropanal was coupled with the Reformatsky reagent 3 with high diastereoselectivity (de > 98%) to give (SS)-4a as the major isomer. The amino alcohol residue of the coupling product 4 was oxidatively cleaved with sodium periodate in the presence of methylamine. An unusual selective oxidative cleavage of the (SS)-isomer was observed and the imine 6 was obtained with ee > 99% while the (RS)-4b isomer was not cleaved. Reaction with p-toluenesulfonic acid monohydrate allowed for the hydrolysis of the imine and the isolation of the amine as its salt. The title compound 1 was then obtained by transesterification, desilylation, and hydrochloride salt formation in a one-pot process. The method was successfully applied toward the synthesis of a wide variety of beta-amino esters.

Abstract
In this paper, the use of penicillin G acylase (PGA) as a biocatalyst and as a chiral selector is described. Penicillin G-acylase is an interesting enzyme used in the manufacture of semisynthetic antibiotics and, in particular, in the production of 6-APA by hydrolysis of penicillin G. Five PGA-based HPLC columns have been prepared by using two different silica supports by employing two immobilization methods, namely "in situ" and "in batch". The effects of the immobilization techniques and of different silica pore size on the catalytic properties of the enzyme as well as the applicability of the PGA-bonded stationary phases as chiral selectors for a number of chiral drugs have been investigated. The HPLC columns based on immobilized PGA combine the hydrolytic activity and the chiral recognition properties of PGA, therefore they have been used for the development of a combined reaction-separation system for chiral and achiral substrates.
