Enzyme Classes
Alcohol Dehydrogenase
Application: A broad range of carbonyl compounds (including aldehydes, aliphatic, aromatic, cyclic ketones, diketones, ketoacetals and ketoesters) can be asymmetrically reduced to their corresponding chiral alcohols with high enantioselectivity using these enzymes.

Aldehyde Reductase
Application: NAD(P) dependent dehydrogenation of primary alcohols to the corresponding aldehydes and inverse reaction to give primary alcohols.
Esterases/Lipases
Application: Enantioselective hydrolysis, synthesis and transesteri-cation of esters of primary, secondary and tertiary alcohols. Enantioselective synthesis/hydrolysis of amides.
Transaminases
Application: Asymmetric reductive amination via amino transfer mechanism, for the synthesis of chiral amines.
Ene Reductase
Application: Stereoselective reduction of alkenes.
Aldehyde Dehydrogenenase
Application: Aldehyde dehydrogenases catalyse the oxidation of aldehydes to their corresponding carboxylic acides with
NAD+NADP+ as cofactor.
Enzymatic system for Cofactor Recycling

Alcohol Dehydrogenases (ADH)
For Biocatalytic Ketone Reduction

Application: Stereoselective reduction of ketones to produce enantiomerically-pure alcohols
o Broad range of ketones reduce with high stereo-selectivity
o Both R and S alcohols can be produced
o Yields often near 100% of theoretical
o Mild conditions; few, if any, side product

Examples of structurally diverse ketones:

Products include:
o Tens of di erent commercially available ketoreductases
o Enzymes sold in convenient screening set for rapid identification of the best biocatalyst for a desired reduction.
o All enzymes available on commercial scale

Esterases
For Biocatalytic Resolution of Chiral Acids 

 

Application:
o Stereoselective hydrolysis of esters
o Stereoselective esteri cation of carboxylic acids
o Can be carried out in organic solvents or aqueous mixtures
o Mild conditions; tolerant of wide range of functionality
Lipases
For the Production of Enantiomerically Pure Amines and Alcohols

 

o Stereoselective acylation of amines
o Rapid access to both R and S stereoisomers
o Can be carried out in organic solvents or aqueous mixtures
