|Sporulation factor IV B protease.|
|Stage IV sporulation protein B.|
|Self-cleaves 52-Val-|-Asn-53, 62-Ala-|-Phe-63 and 74-Val-|-Thr-75 at the N-terminus of SpoIVB|
- This enzyme plays a central role in a regulatory checkpoint (the
sigma(K) checkpoint), which coordinates gene expression during the
later stages of spore formation in Bacillus subtilis.
- The enzyme activates proteolytic processing of a sporulation-specific
sigma factor, pro-sigma(K), to its mature and active form, sigma(K),
- The enzyme is also subject to secondary proteolysis, which presumably
- The enzyme is also essential for the formation of heat-resistant
- Belongs to peptidase family S55.
