In this study the influence of amorphous calcium phosphate (ACP) on the setting of, and the formed apatite crystallite size in, a calcium phosphate cement (CPC) based on alpha-tricalcium phosphate (alpha-TCP) or tetracalcium phosphate (TTCP)/monocalcium phosphate monohydrate (MCPM) was investigated.
The phosphorylase phosphatase activity of the ATP,Mgdependent protein phosphatase is stimulated by p-nitrophenyl phosphate (pNPP). All the active forms of this type of enzyme show this property, which seems to be unrelated to anypNPP-hydrolyzing activity. The increase in activity is due to an increa
