Purine metabolic pathway. The pathway consists of three main parts: the xanthosine synthesis pathway, the caffeine synthesis pathway and the theacrine synthesis pathway. Enzyme abbreviations are as follows: SAMS (S-adenosylmethionine synthetase); ADK (adenosine Kinase); APRT (adenine phosphoribosyltransferase); AMPD (adenosine monophosphate deaminase); IMPDH (inosine monophosphate dehydrogenase); 5’-NT (5’-nucleotidase); TCS (3-NMT and 1-NMT, tea caffeine synthase); CYP1A2 (cytochrome P450 family 1 subfamily apolypeptide 2); 9-NMT (9-methyltransferase); ALN (allantoinase); URE (urease).
