When we refer to the phosphate - PO4= - ion, the addition / phosphorylation and removal / de-phosphorylation of this phosphate group / moiety (thereby altering the enzyme's shape) is the way that some types of enzymes are turned on or off / activated or deactivated. The Kinase group of enzymes - that control the Cell cycle - is an example.
It depends on the drug and whether it is water or lipid soluble. Many drugs are bound and transported by plasma proteins.
IN certain cases, enzymes are used to denature (or break up) proteins and disrupt the cell wall (in case of plants). These enzymes require magnesium ions as co-factors in order to catalyze the reaction.
