Nalidixic acid, novobiocin, oxolinic acid and nitrofurantoin, each at low concentrations, cause filamentation of Gram-negative bacilli. Filamentation induced by beta-lactam antibiotics has been correlated to the binding of these antibiotics to specific penicillin-binding proteins (PBPs) of the envelope of Gram-negative bacilli. The studies reported herein indicate that the former group of non-beta-lactam antibiotics do not bind to any of the PBPs of Escherichia coli. However, PBP 1a, PBP 4 and PBP 5/6 of the filaments induced by these agents are increased significantly.
