Maltose metabolism of Pseudomonas fluorescens.

PMCID: PMC235891  PMID: 240805

Abstract

Pseudomonas fluorescens W uses maltose exclusively by hydrolyzing it to glucose via an inducible alpha-glucosidase (alpha-D-glucoside glucohydrolase, EC 3.2.1.20). No evidence for phosphorolytic cleavage or oxidation to maltobionic acid was found in this organism. The alpha-glucosidase was totally intracellular and was most active at pH of 7.0. Induction occurred when cells were incubated with maltotriose or maltose. Induction was rapid and easily detectable within the first 5 min after the addition of the inducer. Glucose and its derivatives did not repress induction. Cells growing on DL-alanine or succinate plus maltose exhibited lower levels of alpha-glucosidase than those grown on maltose alone or maltose plus glucose. Induction required both messenger ribonucleic acid and protein synthesis.
