Alterations of spore coat processing and protein turnover in a Bacillus cereus mutant with a defective postexponential intracellular protease.


A mutant with an alteration in the major intracellular serine protease produced by postexponential Bacillus cereus was isolated by screening mutants defective in spore germination. The purified enzyme from the mutant is more labile to heat and alkaline pH than the protease from the wild type. Protease activity appears at the same time as in the wild type… (More)
