Question

what is enzyme steriospecificity with example

Answer 1

Explanation:

A number of enzymes have the ability to discriminate between enantiomeric substrates or products; such enzymes are referred to as stereospecific/stereoselective enzymes. The substrate specificity of these enzymes are further sub-categorized according to the handedness of the substrates they catalyse. For instance, the L-haloacid dehalogenase from Pseudomonas putida S3 which catalyses the stereospecific hydrolysis of only L-isomer of 2-haloacids. Such enzymes are unique and display chiral preferences in specificity i.e. stereospecificity in their catalysis.

Depending on the enzyme, the fast and slow enantiomers can be D- or L-form of the chiral substrate.

Answer 2

Answer:

For instance, the L-haloacid dehalogenase from Pseudomonas putida S3 which catalyses the stereospecific hydrolysis of only L-isomer of 2-haloacids [1]. Such enzymes are unique and display chiral preferences in specificity i.e. stereospecificity in their catalysis. Most compounds in nature are, in fact, chiral.
