General annotation (Comments)

Function	Provides the D-alanine required for cell wall biosynthesis By similarity. HAMAP MF_01201
Catalytic activity	L-alanine = D-alanine. HAMAP MF_01201
Cofactor	Pyridoxal phosphate By similarity. HAMAP MF_01201
Pathway	Amino-acid biosynthesis; D-alanine biosynthesis; D-alanine from L-alanine: step 1/1. HAMAP MF_01201 Cell wall biogenesis; peptidoglycan biosynthesis. HAMAP MF_01201
Sequence similarities	Belongs to the alanine racemase family.
Caution	The gene coding for this protein seems to be defective in strain 91001 where it is interrupted by the insertion of an IS285 element.
