Penicillins 97-108 hypothetical protein Escherichia coli 43-48 10967102-5 2001 The structure is composed of two domains, a penicillin binding domain with a striking similarity to Class A beta-lactamases (TEM-1-like) and a domain of unknown function. Penicillins 44-54 hypothetical protein Escherichia coli 125-130 8285630-2 1993 A comparative kinetic analysis of both the wild-type and the Ala-235 TEM-1 enzymes revealed little effect of this substitution of residue 235 on the turnover of penicillins but a greater effect on the turnover of cephalosporins. Penicillins 161-172 hypothetical protein Escherichia coli 69-74
