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.
This set of rules addresses specific duties of the officers and directors, procedures for meetings, how to amend the bylaws, and other considerations. The articles of incorporation, on the other hand, is a document filed with the state which generally outlines the makeup of the corporation. The bylaws go into much more detail and do not have to be filed with an agency. The basics of corporate bylaws are covered below.
