Because isoflavone dietary supplements are becoming increasingly popular and are frequently advertised as natural alternatives to(More)
Human Dopa decarboxylase (hDDC), a pyridoxal 5'-phosphate (PLP) enzyme, displays maxima at 420 and 335 nm and emits fluorescence at 384 and 504 nm upon excitation at 335 nm and at 504 nm when excited at 420 nm. Absorbance and fluorescence titrations of hDDC-bound coenzyme identify a single pK(spec) of ~7.2. This pK(spec) could not represent the ionization(More)
