The Biosynthesis of Folic Acid. Iv. Enzymatic Synthesis of Dihydrofolic Acid from Guanine and Ribose Compounds.

In 1954, Albert (2) suggested that purmes may be biological precursors of pteridine compounds. This suggestion was made as a result of his demonstration that purines can be transformed chemically into pteridines under mild conditions in the presence of glyoxal. The first experimental evidence that the biogenesis of purines and pteridines are biologically related was provided by Weygand and Wald...

The utilization of purines in the biosynthesis of folic acid.

There is little information on the origin of the pteridine ring of folic acid (1). The possibility that purines contribute to the biosynthesis of this part of the vitamin has been investigated earlier but could not be demonstrated in a number of microorganisms (2). In fact, attempts to demonstrate the conversion of purines to other naturally occurring pteridines have resulted in an impressive n...

Pteridine Metabolism in the Skin of the Tadpole, Rana Catesbeiana.

The apparent structural similarity between purines and pteridines has been the subject of a number of studies attempting to demonstrate a relationship between these compounds in living systems. That a relationship does, in fact, exist has been shown, not only by purine incorporation into a pteridine (l-3), but also by the ability of at least one organism (Alcaligines fuecalis) to degrade a pter...
