| Abstract: | Pseudomonas cepacia NCTC 10743 utilizes arginine as the sole source of carbon and nitrogen for growth. Arginine is degraded to glutamate via succinyl derivatives. The catabolic sequence in this pathway is L-arginine----N2-succinylarginine----N2-succinylornithine--- -N2-succinylglutamate semialdehyde----N2-succinylglutamate----glutamate + succinate. The formation of the enzymes responsible for arginine degradation is regulated not only by induction but also by both carbon and nitrogen catabolite repression. |
