Analysis of the mutant proBA operon from a proline-producing strain of Serratia marcescens.

Journal of general microbiology - 1 Apr 1992

Omori K, Suzuki S, Imai Y, Komatsubara S

Abstract excerpt

The nucleotide sequence of the proBA operon from a proline-hyperproducing mutant of Serratia marcescens was determined. Two base substitutions were found: one in the proB structural gene, coding for gamma-glutamyl kinase (GK), and a second one in the promoter region of the operon. The former base substitution led to a change of the predicted amino acid at position 117 from an alanine to a valine in GK. This...
