Biokatalysatoren für die Geranylierung von Peptiden mit Linearen und Zyklischen Prenylgruppen
Angewandte Chemie, EarlyView.A combination of genome mining, synthetic biology, and biocatalytic assays revealed enzymes that install linear and cyclized prenyl moieties on ribosomally or chemically synthesized peptides. The promiscuity of both enzymes, while being specific for modification of C‐terminal tryptophans, enables enzymatic access to peptide terpenoid hybrids ...
