2.7 Angstrom resolution crystal structure of a probable holliday junction DNA helicase (ruvB) from Campylobacter jejuni subsp. jejuni NCTC 11168 in complex with adenosine-5'-diphosphate
3pfi is a 2 chain structure with sequence from Campylobacter jejuni subsp. jejuni. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
[A3ZGU7_CAMJE] The RuvA-RuvB complex in the presence of ATP renatures cruciform structure in supercoiled DNA with palindromic sequence, indicating that it may promote strand exchange reactions in homologous recombination. RuvAB is a helicase that mediates the Holliday junction migration by localized denaturation and reannealing.[HAMAP-Rule:MF_00016]
