DE   arginine--pyruvate transaminase.
AN   arginine:pyruvate transaminase.
CA   L-arginine + pyruvate = 5-guanidino-2-oxopentanoate + L-alanine.
CC   -!- While L-arginine is the best substrate, the enzyme exhibits broad
CC       substrate specificity, with L-lysine, L-methionine, L-leucine,
CC       L-ornithine and L-glutamine also able to act as substrates, but more
CC       slowly.
CC   -!- Pyruvate cannot be replaced by 2-oxoglutarate as amino-group
CC       acceptor.
CC   -!- This is the first catalytic enzyme of the arginine transaminase
CC       pathway for L-arginine utilization in Pseudomonas aeruginosa.
CC   -!- This pathway is only used when the major route of arginine
CC       catabolism, i.e. the arginine succinyltransferase pathway,
CC       is blocked.
