Determination of effector molecules in L-arabinose-induced bulge formation and lysis of Escherichia coli IFO 3545.

Abstract excerpt

L-Ribulose 5-phosphate (L-Ru5P) was identified as the primary effector molecule of L-arabinose-induced bulge formation in Escherichia coli IFO 3545 observed in nutrient broth with 5% (w/v) sodium chloride. Hyperinduction of L-arabinose isomerase was due to exogenous sodium chloride and the resulting alteration in the balance of the L-arabinose-metabolizing enzymes resulted in accumulation of L-Ru5P. L-Ru5P...
