Discovery of a new P450 enzyme DkpdB for cyclo(Trp-Phe) dimerization in the marine strain Aspergillus sydowii MNP-2.
A novel cytochrome P450 monooxygenase DkpdB was originally discovered in the marine-derived fungus Aspergillus sydowii MNP-2 and shown to catalyze the formation of the DKP dimer WIN 64821 from cyclo(Trp-Phe) through a proposed C3-C3' oxidative coupling reaction.
