(Left) Experimentally observed conformation of the benzylpenicillinoyl moiety of the acyl-enzyme complex formed with Δ1-36 rPBP5. (Right) Modeled conformation of the penicillinoyl moiety of the acyl-enzyme complex formed between Δ1-36 rPBP5 and azlocillin, based on the benzylpenicillin complex. The carbonyl oxygen of the ureido side chain offers H-bonding interactions not present with other β-lactams.
