Functionforms a complex with RUVA. RUVB could possess weak ATPase activity, which will be stimulated by the RUVA protein in the presence of DNA. 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 an helicase that mediates the holliday junction migration by localized denaturation and reanneling.
ProductProbable holliday junction DNA helicase RuvB
CommentsRv2592c, (MTCY227.09), len: 344 aa. Probable ruvB, Holliday junction binding protein (see Mizrahi & Andersen 1998), equivalent to P40833|RUVB_MYCLE|ML0483|B1177_C3_227 holliday junction DNA helicase from Mycobacterium leprae (349 aa), FASTA scores: opt: 2059, E(): 2.1e-106, (94.45% identity in 342 aa overlap). Also highly similar to others e.g. Q9AE09|RUVB from Corynebacterium glutamicum (Brevibacterium flavum) (363 aa), FASTA scores: opt: 1651, E(): 6.5e-84, (75.6% identity in 332 aa overlap); Q9L291|RUVB from Streptomyces coelicolor (357 aa), FASTA scores: opt: 1530, E(): 3e-77, (68.2% identity in 343 aa overlap); P08577|RUVB_ECOLI|B1860|Z2912|ECS2570 from Escherichia coli strains K12 and O157:H7 (336 aa), FASTA scores: opt: 1284, E(): 1e-63, (55.45% identity in 330 aa overlap); etc. Contains PS00017 ATP/GTP-binding site motif A (P-loop). Belongs to the RuvB family.
Functional categoryInformation pathways
TranscriptomicsmRNA identified by microarray analysis and down-regulated after 24h of starvation (see Betts et al., 2002).
MutantEssential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019).Disruption of this gene results in growth defect of H37Rv in vitro, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
