Genetic mapping of loci for glucose-6-phosphate dehydrogenase, gluconate-6-phosphate dehydrogenase, and gluconate-6-phosphate dehydrase in Escherichia coli.
The loci on the Escherichia coli genome of mutations affecting the constitutive enzymes glucose-6-phosphate dehydrogenase (zwf) and gluconate-6-phosphate dehydrogenase (gnd), and the inducible enzyme gluconate-6-phosphate dehydrase (edd), were determined by conjugation and transduction experiments, chiefly by three-factor crosses. They are in the same region of the chromosome, and their order is gnd-his-(edd, zwf)-aroD; gnd and his are cotransduceable, as are zwf and edd. The position of gnd in Salmonella typhimurium was shown to be similar to that in E. coli.
