FCD domain; This domain is the C-terminal ligand binding domain of many members of the GntR family. This domain binds to a range of effector molecules, including Lactate, Zn(II), Ni(II), Ca(II), Mg(II), citrate, sugar acids, sialic acid and N-acetylglucosamine-6-P, that regulate the transcription of genes through the action of the N-terminal DNA-binding domain pfam00392 (Matilla et. al., FEMS Microbiology Reviews, fuab043, 45, 2021, 1. https://doi.org/10.1093/femsre/fuab043). This domain is found in Swiss:P45427 and Swiss:P31460 that are regulators of sugar biosynthesis operons. It is also in the known structure of FadR where it binds to acyl-coA, the domain is alpha helical. This family has been named as FCD for (FadR C-terminal Domain).

This entry represents the C-terminal ligand binding domain of many members of the GntR family; This domain probably binds to a range of effector molecules that regulate the transcription of genes through the action of the N-terminal DNA-binding domain. This domain is found in and that are regulators of sugar biosynthesis operons. Many bacterial transcription regulation proteins bind DNA through a helix-turn-helix (HTH) motif, which can be classified into subfamilies on the basis of sequence similarities. The HTH GntR family has many members distributed among diverse bacterial groups that regulate various biological processes. It was named GntR after the Bacillus subtilis repressor of the gluconate operon. In general, these proteins contain a DNA-binding HTH domain at the N terminus, and an effector binding or oligomerisation domain at the C terminus. The winged-helix DNA-binding domain is well conserved in structure for the whole of the GntR family, and is similar in structure to other transcriptional regulator families. The C-terminal effector-binding and oligomerisation domains are more variable and are consequently used to define the subfamilies. Based on the sequence and structure of the C-terminal domains, the GtnR family can be divided into four major groups, as represented by FadR, HutC, MocR and YtrA, as well as some minor groups such as those represented by AraR and PlmA.

Winged helix-turn-helix (WHTH) DNA-binding domain of the GntR family of transcriptional regulators; This CD represents the winged HTH DNA-binding domain of the GntR (named after the gluconate operon repressor in Bacillus subtilis) family of bacterial transcriptional regulators and their putative homologs found in eukaryota and archaea. The GntR family has over 6000 members distributed among almost all bacterial species, which is comprised of FadR, HutC, MocR, YtrA, AraR, PlmA, and other subfamilies for the regulation of the most varied biological process. The monomeric proteins of the GntR family are characterized by two function domains: a small highly conserved winged helix-turn-helix prokaryotic DNA binding domain in the N-terminus, and a very diverse regulatory ligand-binding domain in the C-terminus for effector-binding/oligomerization, which provides the basis for the subfamily classifications. Binding of the effector to GntR-like transcriptional regulators is presumed to result in a conformational change that regulates the DNA-binding affinity of the repressor. The GntR-like proteins bind as dimers, where each monomer recognizes a half-site of 2-fold symmetric DNA sequences. Pssm-ID: 153418 [Multi-domain] Cd Length: 66 Bit Score: 39.35 E-value: 8.94e-05

Bacterial regulatory proteins, gntR family; This family of regulatory proteins consists of the N-terminal HTH region of GntR-like bacterial transcription factors. At the C-terminus there is usually an effector-binding/oligomerization domain. The GntR-like proteins include the following sub-families: MocR, YtrR, FadR, AraR, HutC and PlmA, DevA, DasR. Many of these proteins have been shown experimentally to be autoregulatory, enabling the prediction of operator sites and the discovery of cis/trans relationships. The DasR regulator has been shown to be a global regulator of primary metabolism and development in Streptomyces coelicolor.
