CcpA-independent regulation of expression of the Mg2+ -citrate transporter gene citM by arginine metabolism in Bacillus subtilis.

abstract：:Penicillin-binding proteins were identified in Borrelia burgdorferi membranes. A 94-kilodalton penicillin-binding protein was the first to be labeled with tritiated penicillin and was the first band to disappear in a competition experiment. Its binding ability was destroyed when membranes were preboiled. In addition, ...
