Breaking Cyclic Dipeptide Prenyltransferase Regioselectivity by Unnatural Alkyl Donors
摘要:
The behavior of five cyclic dipeptide prenyltransferases, responsible for C2-regular, C2-reverse, or C3-reverse prenylation, was investigated In the presence of the unnatural alkyl donors monomethylallyl and 2-pentenyl diphosphate. Both substrates were well accepted by the tested enzymes. Interestingly, C2-reverse and C3-reverse monoalkylated derivatives were identified as enzyme products In all of the enzyme assays. These findings indicate their similar reaction characteristics in the presence of unnatural alkyl donors.
