ID 1.4.99.6 DE D-arginine dehydrogenase. AN D-amino-acid dehydrogenase. CA A + D-arginine + H2O = 5-guanidino-2-oxopentanoate + AH2 + NH4(+). CC -!- The enzyme, which has been isolated from the bacterium Pseudomonas CC aeruginosa PAO1, forms with EC 1.4.1.25 a two-enzyme complex involved CC in the racemization of D- and L-arginine. CC -!- The enzyme has a broad substrate range and can act on most D-amino CC acids with the exception of D-glutamate and D-aspartate. CC -!- However, activity is maximal with D-arginine and D-lysine. CC -!- Not active on glycine. CC -!- Formerly EC 1.4.99.1. DR Q9HXE3, DAUA_PSEAE ; //
