Influence of various inhibitors on alkaline phosphatase in calicifying hamster molars, employing paranitrophenyl phosphate as substrate
J. H. Woltgens
In mineralizing hamster molars, the influence of several inhibitors on
p-NPP-ase has been demonstrated, and compared with their effect on PPi-ase,
known to belong to the same enzyme. Whereas the latter activity is much
more physiological, p-NPP is a better substrate to distinguish between the
effects of bivalent cations on the enzyme or the substrate.
