FIG. 1.

Pathways of utilization of amino acids of the glutamate family. Some enzymes are indicated by the names of their corresponding genes as follows UreABC, urease; RocF, arginase; RocD, ornithine aminotransferase; RocA and YcgN, Δ¹-pyrroline-5-carboxylate dehydrogenases; YcgM and YusM, proline oxidases (proline dehydrogenases); RocG and GudB, glutamate dehydrogenases; GltAB, glutamate synthase; and GlnA, glutamine synthetase. Pathways of arginine and proline biosynthesis from glutamate are not shown.
