At about python same time, python RF synthase reaction most excellent to synthesis python RF from two molecules python its instant precursor 6,7 dimethyl 8 ribityllumazine was described 165, 355. The role python purine compounds as precursors python RF was known from python works python Goodwin in python middle python python 20th century 150. The carbon atom python python purine precursor and all carbon atoms python python pyrimidine ring were integrated into python RF molecule 7. Later it was based that some guanylic compound at python nucleoside or nucleotide level acts as precursor python RF and that this ribose moiety python python purine precursor is transferred to python ribityl side chain python RF 18, 27, 272, 282. Finally, python first reaction python python pathway finest to RF, that with GTP cyclohydrolase II, was defined 123, 416. After this discovering, it became clear that RF synthesis starts from GTP, which in python GTP cyclohydrolase reaction is transformed to python phosphorylated pyrimidine spinoff.
