| csfB | fin | BSU00240 | BSU00540 | Forespore-specific anti-sigma factor; An anti-sigma-G factor, prevents premature activation of sigma-G factor in the forespore; overexpression leads to 1000-fold reduction in spore formation, spore formation stops after engulfment. Overexpression also inhibits sigma- G transcription activation activity. When both Gin and sigma-G are expressed in E.coli Gin inhibits sigma-G, strongly suggesting Gin inhibits by direct physical interaction. | Protein required for the switch from F to G during sporulation (anti sigma F); An anti-sigma factor for sporulation specific sigma-F factor, by antagonizing sigma-F it allows the switch to sigma-G factor and progression to the late sporulation development stages. Might stabilize or process Holliday junction intermediates, although this may be due to polar effects on the downstream mfd gene. | 0.866 |
