Mechanism of excessive purine biosynthesis in hypoxanthine-guanine phosphoribosyltransferase deficiency.
Certain gouty subjects with excessive de novo purine synthesis are deficient in hypoxanthineguanine phosphoribosyltransferase (HG-PRTase [EC 2.4.2.8]). The mechanism of accelerated uric acid formation in these patients was explored by measuring the incorporation of glycine-(14)C into various urinary purine bases of normal and enzyme-deficient subjects during treatment with the xanthine oxidase ...
متن کاملHypoxanthine-guanine phosphoribosyltransferase variant associated with accelerated purine synthesis.
We have previously described a 14-yr-old boy with hyperuricemia, renal failure, and accelerated purine production resistant in vivo and in vitro to purine analogs. This patient demonstrated normal red cell hypoxanthine-guanine phosphoribosyltransferase (HPRT) heat stability, electrophoresis at high pH, and activity at standard substrate levels. In the present report an abnormal HPRT enzyme was ...

متن کاملHuman hypoxanthine-guanine phosphoribosyltransferase.
A mutant form of human hypoxanthine-guanine phosphoribosyltransferase (HPRTToronto) was isolated from erythrocytes of a male patient with gout due to a partial deficiency of enzyme activity. The tryptic peptides of HPRTToronto were mapped by reverse-phase high pressure liquid chromatography in an attempt to define the precise abnormality in its primary structure. Sequence analysis of the single...
