Glucose inhibition of the transport and phosphoenolpyruvate-dependent phosphorylation of galactose and fructose in Vibrio cholerae

J Bacteriol. 1974 May;118(2):764-7. doi: 10.1128/jb.118.2.764-767.1974.

Abstract

Vibrio cholerae followed a two-step pattern of growth in a medium containing glucose and either galactose or fructose. Glucose was utilized first. Glucose inhibited the uptake and phosphenolpyruvate-dependent phosphorylation of galactose and fructose.
