Abstract

A gene for the constitutive ribosephosphate isomerase (rpiA) is highly cotransducible with serA at 56.2 min on the genetic linkage map of Escherichia coli K-12. Suppression of ribosephosphate isomerase A-negative mutants can occur by a regulator gene mutation permitting constitutive synthesis of the normally inducible ribosephosphate isomerase B.
