From: Engineered P450 biocatalysts show improved activity and regio-promiscuity in aromatic nitration
Both 4-Me-5-NO2-l-Trp and 4-Me-7-NO2-l-Trp were produced in the TB14 reaction with 4-Me-dl-Trp as substrate. The aromatic region of 1H NMR spectrum of isolated product showed the chemical shifts of two sets of aromatic protons. Integrated values of these protons were also included.
