Fl

B-Lactama - The effect of FL 1060 (la), a 60-asildlnopenicillanlc acid, on E. coli was intensely investigated. The morphological changes elicited by this compound differ from the classical penicillin-induced response. 

The three enzymes sensitive to penicillins, i.e., peptidoglycan transpeptidase, D-alanine earboxypeptldase, and endopeptidase, were not inhibited at bactericidal concentrations of FL 1060 , but the formation of peptido-glycans covalently bound to the cell wall or to lipoproteins was impaired.

Theresultsgivenbelowarebasedonstandardparametervalues Vq = 1-56 x 10 a.u., fl = 1.36 a.u., mass m = 1060 a.u., and reaction coordinate = x. The exact quantum mechanical (QM) rate constant kq for this reaction can be obtained by integrating the exact quantum mechanical cumulative reaction probability, which is known analytically [30,78].
