Isolation and Characterization of a Mutation That Alters the Substrate Specificity of the Escherichia Coli Glucose Permease
Overview
Affiliations
We isolated 10 mannitol-positive mutants from a mannitol-negative Escherichia coli strain. These mutations mapped within ptsG, encoding the glucose permease (EIIGlc), and resulted in a G-320-to-V substitution that allows EIIGlc to transport mannitol. Gly-320 lies within a putative transmembrane helix of EIIGlc that may be involved in substrate recognition.
