RL J. Bacteriol. 193:116-124(2011).
CC -!- FUNCTION: An anti-sigma factor for sporulation specific sigma-F factor,
CC by antagonizing sigma-F it allows the switch to sigma-G factor and
CC progression to the late sporulation development stages
CC (PubMed:21037003). Might stabilize or process Holliday junction
CC intermediates, although this may be due to polar effects on the
CC downstream mfd gene (PubMed:15317759). {ECO:0000269|PubMed:15317759,
CC ECO:0000269|PubMed:21037003}.
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000305|PubMed:21037003};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:21037003}.
CC -!- DEVELOPMENTAL STAGE: Diffusely expressed in the forespore throughout
CC spore development. {ECO:0000269|PubMed:21037003}.
CC -!- INDUCTION: Induced at 2 hours after sporulation onset as part of the
CC sigma-F regulon, followed by further induction after 3 hours as part of
CC the sigma-G regulon; its concentration rises throughout sporulation (at
CC protein level) (PubMed:21037003). {ECO:0000269|PubMed:21037003}.
CC -!- DISRUPTION PHENOTYPE: Cells missing this gene prolong the activity of
CC sigma-F factor and do not fully induce the activity of sigma-G factor;
CC sporulation efficiency is reduced 50-fold with most spores arresting in
CC the engulfment stage (III) (PubMed:21037003). About 10-fold increased
CC sensitivity to DNA damaging agents, 60% reduced chromosomal DNA
CC transformation; plasmid transformation is unaffected. Partially
CC suppresses DNA damaging agent sensitivity of recU deletions
CC (PubMed:11810266). Partially suppresses DNA damaging agent sensitivity
CC of recU deletions (PubMed:11810266). Partially suppresses DNA repair
CC and chromosome segregation defects in ruvA and recG mutants cells, but
CC not in recD or recU mutant cells (PubMed:15317759).
CC {ECO:0000269|PubMed:11810266, ECO:0000269|PubMed:15317759,
CC ECO:0000269|PubMed:21037003}.
CC -!- CAUTION: Recombination phenotypes may be due to polar effects on the
CC downstream gene mfd rather than due to loss of the anti-sigma factor
CC (PubMed:21037003). {ECO:0000305|PubMed:21037003}.
