RNASE H FROM BACTERIOPHAGE T4
Overview
Bacteriophage T4 RNase H is a 5' to 3' exonuclease that removes RNA primers from the lagging strand of the DNA replication fork and is a member of the RAD2 family of eukaryotic and prokaryotic replication and repair nucleases. The crystal structure of the full-length native form of T4 RNase H has been solved at 2.06 angstroms resolution in the presence of Mg2+ but in the absence of nucleic acids. The most conserved residues are clustered together in a large cleft with two Mg2+ in the proposed active site. This structure suggests the way in which the widely separated conserved regions in the larger nucleotide excision repair proteins, such as human XPG, could assemble into a structure like that of the smaller replication nucleases.
