Relative order of glg mutations affecting glycogen biosynthesis in Escherichia coli K12

Abstract
Mutations affecting the glycogen biosynthesis in E. coli can be mapped at three different loci, glg A, glg B and glg C lying between asd and mal A. Transduction tests suggest the following order for the genes in this region: mal A-glg A-glg C-gla B-asd.
