The protein

Catalyzed reaction/ biological activity

• processing of pro-sigma-K to active [protein|24F7FD5C7C3A68BB2760ABB8CBD8FBD65E5FF7D4|SigK] [Pubmed|19805276]

Protein family

• peptidase M50B family (according to Swiss-Prot)

[SW|Domains]

• C-terminal cystathionine-beta-synthase (CBS) domain, this domain binds ATP [Pubmed|19805276]

Effectors of protein activity

• ATP regulates substrate access to the active site and renders cleavage sensitive to the cellular energy level [Pubmed|19805276]

[SW|Localization]

• integral membrane protein [Pubmed|11959848]
• mother cell membrane [Pubmed|24243021]
