The distribution of GTP-cyclohydrolase I, pyruvoyl tetrahydropterin (dysopropterin) synthase, and pyruvoyl tetrahydropterin reductase in goldfish erythrophores, melanophores, and erythrophoroma cells in vitro has been revealed by specific biochemical assays. The activity of pyruvoyl tetrahydropterin synthase in the erythrophores is nearly the same as that in rat kidney and pineal gland. Results of the simultaneous quantification of unconjugated pteridines (biopterin, sepiapterin, neopterin, and… CONTINUE READING
