An enzymatic method for preparing 6R-[U-14C]-tetrahydrobiopterin from [U-14C]GTP is presented. This method utilizes purified preparations of three biosynthetic enzymes for 6R-tetrahydrobiopterin, i.e., Escherichia coli GTP cyclohydrolase I, rat 6-pyruvoyl-tetrahydropterin synthase, and rat sepiapter
## Abstract A procedure for the facile preparation of labelled carboxylic acids from labelled Ξ±βamino acids has been described. The reaction is attractive for the small scale synthesis of such compounds.
## 8-Azaguanosine I4C-labeled in the ribose moiety was enzymatically synthesized in two steps: 2 ) synthesis of 8-azaguanosine from [ U-14C]ribose-l-phosphate and 8-azaguanine catalyzed by purine nucleoside phosphorylase. The radiochemical yield was 708, and no contaminants were present in the is
