Nucleotidyltransferase (NT) domain of Escherichia coli adenylyltransferase (GlnE), Escherichia coli uridylyl transferase (GlnD), and similar proteins; Escherichia coli GlnD and -E participate in the Glutamine synthetase (GS)/Glutamate synthase (GOGAT) pathway for the assimilation of ammonium nitrogen. In nitrogen sufficiency, GlnE adenylates GS, reducing GS activity; when nitrogen is limiting, GlnE deadenylates GS-AMP, restoring GS activity. When nitrogen is limiting, GlnD uridylylates the nitrogen regulatory protein PII to PII-UTP, and in nitrogen sufficiency, it removes the modifying groups. The activity of Escherichia coli GlnE is modulated by PII-proteins. PII-UMP promotes GlnE deadenylation activity, and PII promotes GlnE adenylation activity. Escherichia coli GlnE has two separate NT domains. The N-terminal NT domain catalyzes the deadenylylation of GS, and the C-terminal NT domain the adenylylation reaction. The majority of proteins in this family contain a C-terminal NT domain which is associated with a cystathionine beta-synthase (CBS) domain pair and a CAP_ED (cAMP receptor protein effector ) domain. This family belongs to the Pol beta-like NT superfamily. In the majority of enzymes in this superfamily, two carboxylates, Dx[D/E], together with a third more distal carboxylate, coordinate two divalent metal cations involved in a two-metal ion mechanism of nucleotide addition. For the majority of proteins in this family, these carboxylate residues are conserved.

GlnD PII-uridylyltransferase; This is a family of bifunctional uridylyl-removing enzymes/uridylyltransferases (UR/UTases, GlnD) that are responsible for the modification (EC:2.7.7.59) of the regulatory protein P-II, or GlnB (pfam00543). In response to nitrogen limitation, these transferases catalyze the uridylylation of the PII protein, which in turn stimulates deadenylylation of glutamine synthetase (GlnA). Deadenylylated glutamine synthetase is the more active form of the enzyme. Moreover, uridylylated PII can act together with NtrB and NtrC to increase transcription of genes in the sigma54 regulon, which include glnA and other nitrogen-level controlled genes. It has also been suggested that the product of the glnD gene is involved in other physiological functions such as control of iron metabolism in certain species. The region described in this family is found in many of its members to be C-terminal to a nucleotidyltransferase domain (pfam01909), and N-terminal to an HD domain (pfam01966) and two ACT domains (pfam01842).
