Behavior of Penicillin-Binding Proteins in Escherichia coli upon Heat and Detergent Treatments and Partial Purification of Penicillin-Binding Proteins 1A and 1B

Penicillin-binding proteins differ greatly in heat sensitivity and sensitivity to detergents. The partial purification of penicillin-binding 1A and 1B proteins from Escherichia coli is described.
