Application
Alanine racemase is used to convert L-alanine into D-alanine. Alanine racemase, from Sigma, has been used to isomerize L-[U-14C]alanine to a racemic mixture of L/D- [14C]alanine †.
Biochem/physiol Actions
Alanine racemase is involved in alanine, aspartate and D-alanine metabolism. 3-Fluoro-D-alanine and D-Cycloserine are known to inhibit alanine racemase.† Alanine racemase monomer is composed of two domains, an eight-stranded α/β barrel at the N-terminus and a C-terminal domain. The N-terminus includes residues 1-240, whereas the C-terminal comprises of the β-strand (residues 241-388). One molecule of pyridoxalphosphate (PLP) is present as the cofactor in each subunit.†
Physical form
Aqueous solution containing 10 mM potassium phosphate
Other Notes
One unit will convert 1.0 μmole of D -alanine to L -alanine per minute at pH 10.5 at 30 °C in a coupled assay system with L -alanine dehydrogenase.
