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.
In terms of governance, ownership, capital generation, and liability, S corporations and C corporations are quite similar. At the end of the day, both of them are still corporations. The S vs. C distinction is really just a âstatusâ that comes with differences in taxation and flexibility of ownership.
