L-arginine degradation (S)-2-amino-5-guanidinovaleric acid degradation 2-amino-5-(diaminomethylidene amino)pentanoic acid degradation Degradation of L-arginine, an energy-rich amino-acid that can supply nitrogen, carbon and energy to various bacteria in a variety of environment. L-arginine can be catabolized by a large number of routes including the arginase pathway, the arginine deiminase (ADI) pathway, the arginine succinyl transferase (AST) pathway, the arginine decarboxylase (ADC), transaminase, oxidase and oxygenase pathways. These pathways often have distinctive functions. UPa:UPA00073 pathway GO:0006527 2-amino-5-(carbamimidamido)pentanoic acid degradation amino-acid degradation L-arginine metabolism
