Anti-sigma-I factor RsgI1

UniProtKB accession:  A3DBH1

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Anti-sigma factor for SigI1. Negatively regulates SigI1 activity through direct interaction (PubMed:20937888). Binding of the polysaccharide substrate to the extracellular C-terminal sensing domain of RsgI1 may induce a conformational change in its N-terminal cytoplasmic region, leading to the release and activation of SigI1 (Probable).
