6-Phosphogluconate dehydrogenase (PGD) genetics in the mouse: linkage with metabolically related enzyme loci
Abstract
An electrophoretic polymorphism of 6-phosphogluconate dehydrogenase (PGD) has been observed in the subspecies Mus musculus musculus from northern Denmark. M. m. musculus is interfertile with inbred strains of mice, and F1 hybrids with C57BL/6J show a three-banded phenotype. This pattern is consistent with a dimeric enzyme structure with codominant expression of alleles. In backcrosses and the F2 generation, PGD segregated as a singly autosomal gene, designated Pgd, closely linked to Gpd-1 on chromosome 4(1.7 +/- 1.1%). Both gene products are dimers, both require NADP, and these enzymes catalyze sequential steps in metabolism.
