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.
洋葱伯克霍尔德菌NCTC 10743利用精氨酸作为生长所需的唯一碳源和氮源。精氨酸通过琥珀酰衍生物降解为谷氨酸。该途径中的分解代谢顺序为:L-精氨酸→N2-琥珀酰精氨酸→N2-琥珀酰鸟氨酸→N2-琥珀酰谷氨酸半醛→N2-琥珀酰谷氨酸→谷氨酸+琥珀酸。负责精氨酸降解的酶的形成不仅受到诱导的调节,还受到碳和氮分解代谢物阻遏的调节。
