Glutamate synthase, large subunit. Similar to sprot|GLXD_RHIME (87%). Glutamate synthase (GltS) is a complex iron-sulphur flavoprotein that catalyses the reductive synthesis of L-glutamate from 2-oxoglutarate and L-glutamine via intramolecular channelling of ammonia, a reaction in the bacterial, yeast and plant pathways for ammonia assimilation. Pfam: Conserved region in glutamate synthase; Specificity unclear.

Glutamine amidotransferase, class-II protein, glxB (purF). Similar to sprot|GLXB_RHIME (46%) and to trembl|Q882P3 (49%). Glutamine amidotransferase catalyse the removal of the ammonia group from glutamine and then to transfer this group to a substrate to form a new carbon-nitrogen group. This catalytic activity is known as glutamine amidotransferase (GATase). On the basis of sequence similarities two classes of GATase domains have been identified class-I and class-II (also known as purF-type). Enzymes containing Class-II GATase domains include amido phosphoribosyltransferase, which cat [...]

Glutamine synthetase III plays an essential role in the metabolism of nitrogen by catalyzing the condensation of glutamate and ammonia to form glutamine. Similar to trembl|Q98A06 (58%) and to sprot|GLN3_RHILP (38%). Pfam (PF03951): Glutamine synthetase, beta-Grasp domain Pfam(PF00120): Glutamine synthetase, catalytic domain; High confidence in function and specificity.

NAD(+) synthase (glutamine-hydrolyzing); Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source.

Amino-acid N-acetyltransferases acting mainly on glutamate in the first step of the 'acetylated' ornithine biosynthesis pathway. For this reason it is also called N-acetylglutamate synthase. The enzyme may also act on aspartate. Similar to sprot|ARGA_YERPE (44%) and to sprot|ARGA_ECOLI (43%). Pfam (PF00696): Aspartokinase superfamily Pfam (PF00583): GCN5-related N-acetyltransferase; Specificity unclear.
