Biochemical characterization of Erythroxylum coca CYP79D62 and CYP79D63. The genes were heterologously expressed in Saccharomyces cerevisae and microsome preparations containing the recombinant proteins were incubated with the potential amino acid substrates L-Phe, L-Tyr, L-Trp, L-Leu, and L-Ile. The respective reaction products of each substrate are depicted sequentially next to their LC-MS/MS traces
