L-arabinose isomerase formation in a conditional mutant of gene araA of Escherichia coli B-r.

Abstract

A temperature-sensitive mutant of Escherichia coli in which the synthesis of l-arabinose isomerase is blocked during growth at 42 C was found to possess the following properties. (i) The mutation occurred in the structural gene for the isomerase, gene araA. (ii) During growth at elevated temperatures the mutant accumulates a product which is a precursor to… (More)
