1c1k is a 1 chain structure with sequence from Escherichia virus T4. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
HLOAD_BPT4 DNA helicase loader protein that participates in viral DNA replication, recombination, and repair (PubMed:10871615). At the fork, required for loading of the replicative helicase onto DNA protected by the ssDNA-binding protein (PubMed:11459967, PubMed:7806533, PubMed:10871615, PubMed:22427673). Coordinates simultaneous synthesis of leading- and lagging-strands (PubMed:11459969).[HAMAP-Rule:MF_04156][1][2][3][4][5]
