[[http://www.uniprot.org/uniprot/DDA_BPT4 DDA_BPT4]] DNA helicase that stimulates viral DNA replication and recombination. Plays a role in T4 DNA replication initiation by selecting and activating DNA origins. Acts by dissociating and reassociating with the DNA molecule being unwound. Unwinds DNA as a monomer in a 5'-to-3' direction at a rate of 250 bp/s and can efficiently displace proteins from the DNA.<ref>PMID:12411580</ref> <ref>PMID:18314134</ref> <ref>PMID:22504228</ref>
