NOVEL REAGENTS FOR CREATINE KINASE

The purpose of this investigation was to develop a simple colorimetric method for creatine kinase (CK). The new method is based on the reaction of creatine, formed enzymatically from creatine phosphate and ADP, with different glyoxal compounds. Hydrated glyoxals, such as para-nitrophenyl, 2-thiophene, 4- biphenyl, 4, 4' -biphenyl,α-naphthyl, β-naphthyl, para-chlorophenyl, and styryl were...

Xanthine Oxidase. Vii. Inhibition by Amino Group Reagents.

In the previous paper (1) milk xanthine oxidase was reported to oxidize quaternary, heterocyclie compounds only at pH values above 9.6, whereas purines and aldehydes are most rapidly oxidized at neutral pH. This specificity change was attributed to an alteration in the substrate-binding site brought about by the titration of a group or groups with a pK, value of about 10.7. This suggestion prom...
