Summary:
This arginine catabolic pathway has been discovered in Escherichia coli K-12 by Shaibe et al. [Shaibe85]. The pathway is essentially identical to an anabolic pathway that is used by many bacteria for the biosynthesis of putrescine (see putrescine biosynthesis I [Morris70]. Even though the main catabolic arginine pathway of Escherichia coli K-12 is the succinyltransferase pathway (arginine degradation II (AST pathway)), this pathway provides an alternative route, and is used under certain growth conditions. Interestingly, unlike Escherichia coli K-12, wild-type E. coli strains are unable to use L-arginine as a carbon source, even though they can use it as a nitrogen source [Cunin86].

Escherichia coli K-12 has two forms of the enzyme arginine decarboxylase: a constitutive biosynthetic form, encoded by the speA gene, and an inducible catabolic form, encoded by the adiA gene. When the catabolic form is not expressed, the pathway operates only in an anabolic manner, catalyzing the biosynthesis of putrescine, which is used by the bacteria either directly or as a precursor for the biosynthesis of other polyamines (see superpathway of polyamine biosynthesis I). However, when the cells are grown in an arginine-rich medium, especially if the medium is acidic and conditions are semi-anaerobic, the catabolic arginine decarboxylase is expressed, and the pathway operates in a catabolic manner, feeding putrescine via 4-aminobutanoate and succinate into the TCA cycle I (prokaryotic) [Tabor85].

Superpathways: superpathway of arginine, putrescine, and 4-aminobutyrate degradation , superpathway of arginine and ornithine degradation

Variants: arginine degradation II (AST pathway)
