abstract：:Studies of gene expression using fusions to lacZ demonstrated that the Bacillus subtilis dacB gene, encoding penicillin-binding protein 5*, is in an operon with two downstream genes, spmA and spmB. Mutations affecting any one of these three genes resulted in the production of spores with reduced heat resistance. The c...
