Glyceraldehyde-3-Phosphate Dehydrogenase Variants in Phyletically Diverse Organisms

Electrophoretically distinct forms of glyceraldehyde-3-phosphate dehydrogenase (TDH) have been detected in turtle, perch, trout, spinach, and yeast. Multiple forms were not detected in rat, rabbit, chicken, frog, honey bee, Euglena, or Escherichia coli. The combination of two different subunits into tetramers is a probable explanation for the five-membered sets usually detected in extracts exhibiting TDH multiplicity.
