Glyceraldehyde 3-p dehydrogenase, glycerate 3-P kinase and enolase mutants of Escherichia coli: genetic studies.

The genetic loci for two enzymes of glycolysis have been established by transductional crosses. The eno locus, likely to be the structural gene for enolase maps in the 52-minute region of the Escherichia coli chromosome. A structural determinant for glycerate 3-P kinase (pgk) is located near serA. The map order is speB-pgk-serA-lysA-argA-eno-cysC. In the 35-minute region maps a locus affecting the structure of glyceraldehyde 3-P dehydrogenase.
