 2-31 2.21e-05

Helix-turn-helix domain of Hin and related proteins; This domain model summarizes a family of DNA-binding domains unique to bacteria and represented by the Hin protein of Salmonella. The basic HTH domain is a simple fold comprised of three core helices that form a right-handed helical bundle. The principal DNA-protein interface is formed by the third helix, the recognition helix, inserting itself into the major groove of the DNA. A diverse array of HTH domains participate in a variety of functions that depend on their DNA-binding properties. HTH_Hin represents one of the simplest versions of the HTH domains; the characterization of homologous relationships between various sequence-diverse HTH domain families remains difficult. The Hin recombinase induces the site-specific inversion of a chromosomal DNA segment containing a promoter, which controls the alternate expression of two genes by reversibly switching orientation. The Hin recombinase consists of a single polypeptide chain containing a C-terminal DNA-binding domain (HTH_Hin) and a catalytic domain.

RNA polymerase sigma-70 factor, Bacteroides expansion family 1; This group of sigma factors are members of the sigma-70 family (TIGR02937) and are found primarily in the genus Bacteroides. This family appears to have resulted from a lineage-specific expansion as B. thetaiotaomicron VPI-5482, Bacteroides forsythus ATCC 43037, Bacteroides fragilis YCH46 and Bacteroides fragilis NCTC 9343 contain 25, 12, 24 and 23 members, respectively. There are currentlyonly two known members of this family outside of the Bacteroides, in Rhodopseudomonas and Bradyrhizobium.

 2-31 1.09e-04

C-terminal DNA-binding domain of LuxR-like proteins. This domain contains a helix-turn-helix motif and binds DNA. Proteins belonging to this group are response regulators; some act as transcriptional activators, others as transcriptional repressors. Many are active as homodimers. Many are two domain proteins in which the DNA binding property of the C-terminal DNA binding domain is modulated by modifications of the N-terminal domain. For example in the case of Lux R which participates in the regulation of gene expression in response to fluctuations in cell-population density (quorum-sensing), a signaling molecule, the pheromone Acyl HSL (N-acyl derivatives of homoserine lactone), binds to the N-terminal domain and leads to LuxR dimerization. For others phophorylation of the N-terminal domain leads to multimerization, for example Escherichia coli NarL and Sinorhizobium melilot FixJ. NarL controls gene expression of many respiratory-related operons when environmental nitrate or nitrite is present under anerobic conditions. FixJ is involved in the transcriptional activation of nitrogen fixation genes. The group also includes small proteins which lack an N-terminal signaling domain, such as Bacillus subtilis GerE. GerE is dimeric and acts in conjunction with sigmaK as an activator or a repressor modulating the expression of various genes in particular those encoding the spore-coat. These LuxR family regulators may share a similar organization of their target binding sites. For example the LuxR dimer binds the lux box, a 20bp inverted repeat, GerE dimers bind two 12bp consensus sequences in inverted orientation having the central four bases overlap, and the NarL dimer binds two 7bp inverted repeats separated by 2 bp.

RNA polymerase sigma-70 factor, Bacteroides expansion family 1; This group of sigma factors are members of the sigma-70 family (TIGR02937) and are found primarily in the genus Bacteroides. This family appears to have resulted from a lineage-specific expansion as B. thetaiotaomicron VPI-5482, Bacteroides forsythus ATCC 43037, Bacteroides fragilis YCH46 and Bacteroides fragilis NCTC 9343 contain 25, 12, 24 and 23 members, respectively. There are currentlyonly two known members of this family outside of the Bacteroides, in Rhodopseudomonas and Bradyrhizobium.

putative zinc finger/helix-turn-helix protein, YgiT family; This model describes a family of predicted regulatory proteins with a conserved zinc finger/HTH architecture. The amino-terminal region contains a novel domain, featuring two CXXC motifs and occuring in a number of small bacterial proteins as well as in the present family. The carboxyl-terminal region consists of a helix-turn-helix domain, modeled by pfam01381. The predicted function is DNA binding and transcriptional regulation.
