The Bacillus subtilis signaling protein SpoIVB defines a new family of serine peptidases.

Journal of bacteriology - 1 Jan 2002

Hoa Ngo T, Brannigan James A, Cutting Simon M

Abstract excerpt

The protein SpoIVB plays a key role in signaling in the final sigma(K) checkpoint of Bacillus subtilis. This regulatory mechanism coordinates late gene expression during development in this organism and we have recently shown SpoIVB to be a serine peptidase. SpoIVB signals by transiting a membrane, undergoing self-cleavage, and then by an unknown mechanism activating a zinc metalloprotease, SpoIVFB, which cleaves...
