PII-like signal transmitter proteins are involved in the regulation of ammonium assimilation and nitrogen fixation. The PII-like proteins differed from each other in details of N-sensing. They were covalently modified by uridylylation upon nitrogen limitation. Similar to trembl|Q9EZQ2 (100%) and to trembl|Q8XWX5 (82%). Pfam: Nitrogen regulatory protein P-II; High confidence in function and specificity.

Probable protein GlxC. Similar to sprot|GLXC_RHIME (59%) and to pir|A96211 (51%). Pfam (PF01493): GXGXG; Family membership.

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.

Nitrogen regulation protein NR(II),; High confidence in function and specificity.

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 [...]
