Function

[UVSW_BPT4] DNA helicase that catalyzes branch migration and dissociation of RNA-DNA hybrids. Plays a critical role in a specific recombination pathway involving simple reciprocal exchange. UvsW protein is normally the key regulatory factor in the switch from early to late phage DNA replication.

Evolutionary Conservation

Publication Abstract from PubMed

In bacteriophage T4, the WXY system repairs DNA damage by a process that involves homologous recombination. This system comprises three proteins, the RecA-like recombination protein UvsX, a recombination mediator protein UvsY, and a helicase UvsW. Here we report the 2.0 A resolution crystal structure of the N-terminal two domains of the UvsW helicase (UvsWNF; residues 1-282). The structure reveals a typical helicase RecA-like domain linked to a small N-terminal alpha/beta domain that likely binds the nucleic acid substrate. The missing C-terminal portion of UvsW almost certainly corresponds to the second RecA-like domain typically found in monomeric helicases. The putative substrate binding domain is unique within the known helicase structures, and it resembles the novel "double-wing" DNA binding domain from the phage T4 MotA transcription factor that mediates the expression of T4 middle genes. The functional implications of this homology for the role of UvsW in T4 DNA metabolism are discussed.
