This arginine catabolic pathway has been discovered in Pseudomonas aeruginosa by Mercenier et al [Mercenier80]. The pathway is essentially identical to an anabolic pathway that is used by higher plants, and many bacteria, for the biosynthesis of putrescine (see putrescine biosynthesis II [Smith64, Piotrowski03]. However, there are indications that in Pseudomonas aeruginosa the pathway also operates in a catabolic form, where the putrescine formed from arginine is degraded further to provide the bacteria with carbon and nitrogen. When grown on arginine as the sole carbon and nitrogen source, the activity of arginine decarboxylase increased significantly, and the addition of agmatine and N-carbamoylputrescine increased the synthesis of agmatine deiminase and N-carbamoylputrescine amidohydrolase. In addition, adding succinate, citrate, glutamine, or ammonia to the medium led to the repression of these enzymes, indicating that the pathway is regulated by both carbon catabolite repression as well as nitrogen catabolite repression [Mercenier80].
While there are several reports supporting the function of this pathway as a catabolic arginine degradation pathway [Haas84, Nakada01, Nakada03], it is clear that the main catabolic arginine pathway in Pseudomonads is the succinyltransferase pathway (see L-arginine degradation II (AST pathway)). In addition, unlike the case in Escherichia coli K-12, where there are two varieties of arginine decarboxylase, a biosynthetic variety and a degradative variety, there is no indication for the presence of a homolog of the degradative form in Pseudomonas aeruginosa. Thus, there is still some debate whether this is a true arginine degradation pathway. However, it is agreed that at least the last two steps of the pathway are used for catabolic agmatine degradation [Nakada03].
