• It is the precursor to the antibiotic tabtoxinine ?-lactam.
• T?L is spontaneously isomerized to tabtoxinine-?-lactam ( T?L ), and TblF did not recognize T?L as a substrate, yielding no T?L-Thr.
• Tabtoxin has been shown to be a dipeptide precursor that must undergo hydrolysis by a peptidase to yield the biologically active form, tabtoxinine-p-lactam ( T?L ).
• The dipeptide toxin contains tabtoxinine-?-lactam ( T?L ) linked by a peptide bond to threonine produced, the chlorosis-inducing activity occurs only after hydrolysis of the peptide bond by aminopeptidases of plant or bacterial origin.
