Serine Recombinase (SR) family, Resolvase and Invertase subfamily, catalytic domain; members contain a C-terminal DNA binding domain. Serine recombinases catalyze site-specific recombination of DNA molecules by a concerted, four-strand cleavage and rejoining mechanism which involves a transient phosphoserine linkage between DNA and the enzyme. They are functionally versatile and include resolvases, invertases, integrases, and transposases. Resolvases and invertases affect resolution or inversion and comprise a major phylogenic group. Resolvases (e.g. Tn3, gamma-delta, and Tn5044) normally recombine two sites in direct repeat causing deletion of the DNA between the sites. Invertases (e.g. Gin and Hin) recombine sites in inverted repeat to invert the DNA between the sites. Cointegrate resolution with gamma-delta resolvase requires the formation of a synaptosome of three resolvase dimers bound to each of two res sites on the DNA. Also included in this subfamily are some putative integrases including a sequence from bacteriophage phi-FC1.

 139-181 1.72e-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.

 5-127 4.33e-26

Serine Recombinase family, catalytic domain; a DNA binding domain may be present either N- or C-terminal to the catalytic domain. These enzymes perform site-specific recombination of DNA molecules by a concerted, four-strand cleavage and rejoining mechanism which involves a transient phosphoserine linkage between DNA and serine recombinase. Serine recombinases demonstrate functional versatility and include resolvases, invertases, integrases, and transposases. Resolvases and invertases (i.e. Tn3, gamma-delta, Tn5044 resolvases, Gin and Hin invertases) in this family contain a C-terminal DNA binding domain and comprise a major phylogenic group. Also included are phage- and bacterial-encoded recombinases such as phiC31 integrase, SpoIVCA excisionase, and Tn4451 TnpX transposase. These integrases and transposases have larger C-terminal domains compared to resolvases/invertases and are referred to as large serine recombinases. Also belonging to this family are proteins with N-terminal DNA binding domains similar to IS607- and IS1535-transposases from Helicobacter and Mycobacterium.

Serine recombinase (SR) family, Partitioning (par)-Resolvase subfamily, catalytic domain; Serine recombinases catalyze site-specific recombination of DNA molecules by a concerted, four-strand cleavage and rejoining mechanism which involves a transient phosphoserine linkage between DNA and the enzyme. They are functionally versatile and include resolvases, invertases, integrases, and transposases. This subgroup is composed of proteins similar to the E. coli resolvase found in the par region of the RP4 plasmid, which encodes a highly efficient partitioning system. This protein is part of a complex stabilization system involved in the resolution of plasmid dimers during cell division. Similar to Tn3 and other resolvases, members of this family may contain a C-terminal DNA binding domain.

 139-181 1.72e-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.

Serine Recombinase (SR) family, IS607-like transposase subfamily, catalytic domain; members contain a DNA binding domain with homology to MerR/SoxR located N-terminal to the catalytic domain. Serine recombinases catalyze site-specific recombination of DNA molecules by a concerted, four-strand cleavage and rejoining mechanism which involves a transient phosphoserine linkage between DNA and the enzyme. They are functionally versatile and include resolvases, invertases, integrases, and transposases. This subfamily is composed of proteins that catalyze the transposition of insertion sequence (IS) elements such as IS607 from Helicobacter and IS1535 from Mycobacterium, and similar proteins from other bacteria and several archaeal species. IS elements are DNA segments that move to new sites in prokaryotic and eukaryotic genomes causing insertion mutations and gene rearrangements.
