Chymosin (Rennin) was effectively purified using an AH-Sepharose 4B column. Binding of Streptomyces pepsin inhibitor (acetul-pepstatin) with chymosin was studied spectroscopically. The binding caused ultraviolet difference and CD spectral changes suggesting microenvironmental changes around tryptophan and/or tyrosine residue(s) in chymosin. The fluorescence intensity of a hydrophobic probe, 2-p-toluidinylnaphthalene-6-sulfonate, increased in the presence of chymosin and was further amplified when Streptomyces pepsin inhibitor was added to the chymosin-2-p-toluidinylnaphthalene-6-sulfonate solution. The binding and dissociation-rate constants between chymosin and the inhibitor were determined using 2-p-toluidinylhnaphthalene-6-sulfonate as a probe. The binding constant was determined from the binding and dissociation-rate constants, to be 3.1 . 10(7) M-1 at 25 degrees C, pH 5.5.
