Three common phenotypes of 6-phosphogluconate dehydrogenase (6-PGD) were identified by enzyme visualization following isoelectric focusing in photochemically polymerized polyacrylamide gels whereas in chemically polymerized gels no activity could be detected. Gene frequencies calculated from 429 individuals were 0.915 and 0.085 for 6-PGD*A and 6-PGD*C, respectively, similar to the gene frequencies of Japanese samples previously reported.

UI	MeSH Term	Description	Entries
D007525	Isoelectric Focusing	Electrophoresis in which a pH gradient is established in a gel medium and proteins migrate until they reach the site (or focus) at which the pH is equal to their isoelectric point.	Electrofocusing,Focusing, Isoelectric
D007527	Isoenzymes	Structurally related forms of an enzyme. Each isoenzyme has the same mechanism and classification, but differs in its chemical, physical, or immunological characteristics.	Alloenzyme,Allozyme,Isoenzyme,Isozyme,Isozymes,Alloenzymes,Allozymes

D010641	Phenotype	The outward appearance of the individual. It is the product of interactions between genes, and between the GENOTYPE and the environment.	Phenotypes
D010734	Phosphogluconate Dehydrogenase	An enzyme of the oxidoreductase class that catalyzes the reaction 6-phospho-D-gluconate and NADP+ to yield D-ribulose 5-phosphate, carbon dioxide, and NADPH. The reaction is a step in the pentose phosphate pathway of glucose metabolism.
