Function

RSGI3_ACET2 Anti-sigma factor for SigI3. Negatively regulates SigI3 activity through direct interaction. Binding of the polysaccharide substrate to the extracellular C-terminal sensing domain of RsgI3 may induce a conformational change in its N-terminal cytoplasmic region, leading to the release and activation of SigI3.[UniProtKB:A3DBH1]
