The protein

Protein family

• anti-sigma-W factor family (according to Swiss-Prot)

Effectors of protein activity

• degraded by [protein|CB50289535EA537F63BADD459BD11AA7759A6658|RasP] and [protein|EE3B6B52EA19958E2E46A1545747F5209A6AA036|PrsW] under conditions of alkali shock or in the presence of antimicrobial peptides, respectively. This results in the release of [protein|3D974DD2967C7F8FD4E3C2AF42617B8AE9F0296D|SigW]
