3 On the basis of X-ray structural information, it was previously proposed that tryptophan-191 of yeast cytochrome c peroxidase (CCP) may be important in determining the spectroscopic and catalytic properties of the enzyme [Edwards, S.

5 By use of site-directed mutagenesis and an Escherichia coli expression system, a mutant phenylalanine-191 (F191) CCP was prepared in order to examine the effects of altering the H-bonding and pi-pi interactions that occur between Trp-191 and the iron-coordinated proximal His-175 in the parent enzyme.
