putative pre-16S rRNA nuclease YqgF and RuvX family; Escherichia coli YqgF has been shown to act as a pre-16S rRNA nuclease, presumably as a monomer. It is involved in the processing of pre-16S rRNA during ribosome maturation. The RuvX gene product from Mycobacterium tuberculosis was shown to act, in a dimeric form, as a Holliday junction resolvase (HJR). HJRs endonucleases specifically resolve Holliday junction DNA intermediates during homologous recombination. Holliday junctions are formed by the reciprocal exchange of strands between two DNA duplexes. HJRs occur in archaea, bacteria, and in the mitochondria of certain fungi; they may form homodimers and display structural similarity to RNase H and Hsp70.

 1-112 7.38e-23

Holliday junction resolvase; The central intermediate formed during mitotic and meiotic recombination is a four stranded DNA structure, also known as the Holliday junction (HJ), and its efficient resolution is essential for proper segregation of chromosomes. Resolution of HJs is mediated by a diverse group of DNA structure specific endonucleases known as Holliday junction resolvases (HJR). This entry is specific for RuvX also known as YqgF a family of nucleases which resolves the Holliday junction intermediates in genetic recombination. Studies carried out in M. tuberculosis, have shown that YqgF/RuvX is a genuine HJR analogous to RuvC from E. coli. Furthermore, a single cysteine present in M. tuberculosis RuvX was found to be required for disulfide-bond mediated intermolecular dimerization and HJ resolution activity, suggesting that M. tuberculosis RuvX has adapted its YqgF protein to function like a typical RuvC family HJR.

Likely ribonuclease with RNase H fold; YqgF proteins are likely to function as an alternative to RuvC in most bacteria, and could be the principal holliday junction resolvases in low-GC Gram-positive bacteria. In Spt6p orthologues, the catalytic residues are substituted indicating that they lack enzymatic functions.
