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.
Inc. vs Corp. Though, no distinct difference exists between the two, it canât be used interchangeably. Both enable companies with Limited liability, and both are separate institutions with whom the business entity needs to get registered, in order to use Incorporation or Corporation as part of the company name.
