Abstract
The natural distribution was investigated of enzyme systems capable of forming heptulose phosphate from nucleosides, certain hexose phosphates, and ribose-5-phosphate. These systems occur widely in amphibia, birds, reptiles, and mammals. The materials examined included fungi (Aspergillus niger), bacteria (Serratia mascerans), yeast, germinating mung beans, spinach, and the brain, heart, kidney, liver, lung, intestine, egg, of fish, frog, turtle, chicken, rat, rabbit, mouse, and dog. Among the plants and microorganisms, activity towards nucleosides was absent (except for yeast) while that towards R5P and also G1P, G6P, and M6P was present.
