Which ONE of the following coenzymes is required for the conversion of L-alanine to a racemic mixture of D-and L-alanine ? [2017]

1. Pyridoxal-6-phosphate (B) Thiamine pyrophosphate (C) Coenzyme A (D) Flavin adenine dinucleotide

Dear student
 
Pyridoxal-6-phosphate is the active form of vitamin B6
It acts as coenzyme in many enzymatic reactions. One of the reaction in which it functions as coenzymes is the conversion of L-alanine to a recemic mixture of D- and L-alanine. This reaction is catalyzed by enzyme alanine racemase.
Thus, the correct answer is option A.
