Protein Domain : B transposition protein, C-terminal IPR009084

Type	Domain
Description	Bacteriophage Mu can integrate into the host bacterial genome and replicate via transposition. Mu requires the activity of four proteins for DNA transposition. Two of these proteins are the phage-encoded A and B transposition proteins, while the other two are host-specified accessory factors HU and IHF. These four proteins can form nucleoprotein complexes (transposomes), which enable strand transfer. The stable protein-DNA intermediate is subsequently disassembled prior to DNA replication by host proteins.The Mu B transposition protein is an ATP-dependent, DNA-binding protein required for target capture and immunity, as well as for activating transpososome function [ ]. The C-terminal domain of the B transposition protein is believed to be involved in both DNA-binding and protein-protein contacts with the Mu A transposition protein. The structure of the C-terminal domain consists of four helices in an irregular array [].
