Many post-translational modifications like glycosylation
(http://www.functionalglycomics.org/static/index.shtml)in proteins
fundamentally change the (functional) 'nature' of the protein (as also the
molecular structure of the protein in case of glycosylation through addition of
sugar chains (glycans)).
