Phenotypes of a mutant

• increased sensitivity to lysozyme, this can be suppressed by overexpression of'' [gene|E97C7A219DB059BB634E893CC355A28324C87ADB|oatA]'' [Pubmed|21856855]

The protein

Protein family

• [SW|Sigma-70 factor family] (according to UniProt)

Effectors of protein activity

• activity is controlled by the interaction with [protein|ED1DDA187692683D9862EC0E858B80CD56C48045|RsiV], proteolytic degradation of [protein|ED1DDA187692683D9862EC0E858B80CD56C48045|RsiV] releases active [protein|D04629D798E458AD538809BB2B150B7FA81D2C7E|SigV] [Pubmed|23687273]
