Amino-acid racemase able to utilize a broad range of substrates. Is mostly active with lysine and arginine and, to a lesser extent, with ornithine, whereas is about 10 times less active with alanine, methionine and ethionine. With phenylalanine as substrate only a trace activity is detectable, and is inactive with glutamate. Plays a key role in the catabolism of D-arginine and D-lysine, that allows P.taetrolens strain NBRC 3460 to grow on these basic D-amino acids as a sole carbon source.

Belongs to the alanine racemase family. Bsr subfamily.
