Pyridine nucleotide-disulfide oxidoreductase family protein.

lipoamide_DH: dihydrolipoyl dehydrogenase.

Urea_carbox: urea carboxylase.

2Fe-2S iron-sulfur cluster binding domain protein.

Phosphoribosylformylglycinamidine synthase; Phosphoribosylformylglycinamidine synthase involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate.

Glycine dehydrogenase; The glycine cleavage system catalyzes the degradation of glycine. The P protein binds the alpha-amino group of glycine through its pyridoxal phosphate cofactor; CO(2) is released and the remaining methylamine moiety is then transferred to the lipoamide cofactor of the H protein; Belongs to the GcvP family.

Glutamate-ammonia ligase adenylyltransferase family protein; Involved in the regulation of glutamine synthetase GlnA, a key enzyme in the process to assimilate ammonia. When cellular nitrogen levels are high, the C-terminal adenylyl transferase (AT) inactivates GlnA by covalent transfer of an adenylyl group from ATP to specific tyrosine residue of GlnA, thus reducing its activity. Conversely, when nitrogen levels are low, the N-terminal adenylyl removase (AR) activates GlnA by removing the adenylyl group by phosphorolysis, increasing its activity. The regulatory region of GlnE binds th [...]

Delta-1-pyrroline-5-carboxylate dehydrogenase; Oxidizes proline to glutamate for use as a carbon and nitrogen source; In the C-terminal section; belongs to the aldehyde dehydrogenase family.

Glutamine-fructose-6-phosphate transaminase; Catalyzes the first step in hexosamine metabolism, converting fructose-6P into glucosamine-6P using glutamine as a nitrogen source.
