Functional Family FAD-dependent catabolic D-arginine dehydrogenase DauA

Enzyme Information

1.4.99.6
D-arginine dehydrogenase.
based on mapping to UniProt Q9HXE3
D-arginine + acceptor + H(2)O = 5-guanidino-2-oxopentanoate + NH(3) + reduced acceptor.
-!- The enzyme, which has been isolated from the bacterium Pseudomonas aeruginosa PAO1, forms with EC 1.4.1.25 a two-enzyme complex involved in the racemization of D- and L-arginine. -!- The enzyme has a broad substrate range and can act on most D-amino acids with the exception of D-glutamate and D-aspartate. -!- However, activity is maximal with D-arginine and D-lysine. -!- Not active on glycine. -!- Formerly EC 1.4.99.1.
