CENP-B N-terminal DNA-binding domain

Centromere Protein B (CENP-B) is a DNA-binding protein localised 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 [1].

IS630 transposase-related protein

Transposase proteins are necessary for efficient DNA transposition. This family includes insertion sequences from Synechocystis PCC 6803 three of which are characterised as homologous to bacterial IS5- and IS4- and to several members of the IS630-Tc1-mariner superfamily [1]. [1]. 9305771. Three insertion sequences from the cyanobacterium Synechocystis. PCC6803 support the occurrence of horizontal DNA transfer among. bacteria.. Cassier-Chauvat C, Poncelet M, Chauvat F;.

transposase

Transposase proteins are necessary for efficient DNA transposition. This family consists of various E. coli insertion elements and other bacterial transposases some of which are members of the IS3 family. [1]. 9180700.
