There are very few of Ca dependent proteases. I am not sure kinases need metals as cofactors (activation is a different thing; that's signaling). Alkaline phosphatase needs Zn. But I guess this is not as common as the dependence of nucleases on metal ions. In any case we do use a protein inhibitor cocktail while doing extraction.
Summary. 1  Incorporation and corporation cannot be differentiated as one leads to the other. 2  While incorporation is the process, corporation is the organisation formed out of this process.
A franchise and a corporation can be essentially the same type of business with different growth strategies. A franchise is a satellite business of a parent company owned and operated by a separate business entity under license from the parent company. A corporation owns all its business locations without bringing in other companies.
