| Comment | SpoIVB, the stage IV sporulation protein B of endospore-forming bacteria such as Bacillus subtilis, is a serine proteinase, expressed in the spore (rather than mother cell) compartment, that participates in a proteolytic activation cascade for Sigma-K. It appears to be universal among endospore-forming bacteria and occurs nowhere else. |
