10-62 1.85e-22

CENP-B N-terminal DNA-binding domain; Centromere Protein B (CENP-B) is a DNA-binding protein localized to the centromere. Within the N-terminal 125 residues, there is a DNA-binding region, which binds to a corresponding 17bp CENP-B box sequence. CENP-B dimers either bind two separate DNA molecules or alternatively, they may bind two CENP-B boxes on one DNA molecule, with the intervening stretch of DNA forming a loop structure. The CENP-B DNA-binding domain consists of two repeating domains, RP1 and RP2. This family corresponds to RP1 has been shown to consist of four helices in a helix-turn-helix structure.

11-48 2.22e-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.
