A	PF08335	GlnD PII-uridylyltransferase (GlnD_UR_UTase)	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 (e.g. Swiss:P05826, Pfam:PF00543).

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 (e.g. Swiss:P05826, Pfam:PF00543). In response to nitrogen limitation, these transferases (e.g. Swiss:P27249) catalyse 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 [1]. 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 [2]. 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 [2]. The region described in this family is found in many of its members to be C-terminal to a nucleotidyltransferase domain (Pfam:PF01909), and N-terminal to an HD domain (Pfam:PF01966) and two ACT domains (Pfam:PF01842) [3].
