L-alanine = D-alanine. Ref.1

Cofactor

Pyridoxal phosphate. Ref.1

Pathway

Amino-acid biosynthesis; D-alanine biosynthesis; D-alanine from L-alanine: step 1/1. HAMAP-Rule MF_01201

Cell wall biogenesis; peptidoglycan biosynthesis. HAMAP-Rule MF_01201

Subunit structure

Monomer but homodimer in the presence of the substrate. Ref.1

Sequence similarities

Belongs to the alanine racemase family.

Biophysicochemical properties

pH dependence:

Optimum pH is 8-10. Ref.1

Temperature dependence:

Optimum temperature is 50 degrees Celsius.
