Calostoma cinnabarinum

Pterin

These folate-dependent biosynthetic reactions include the transfer of methyl groups from 5-methyltetrahydrofolate to homocysteine to form formyl groups from 10-formyltetrahydrofolate to N-formylmethionine in initiator tRNAs.

Petunidin

Petunidin could form in the exocarp of fruits from delphinidin, with an anthocyanin flavonoid O-methyltransferase (Catechol-O-methyl transferase) catalyzing the B-ring methylation and S-Adenosyl-L-methyl-3H methionine being the methyl group donor.
