human genome. Consensus also exists that there are two to three fold more number of proteins in human proteome as
compared to the total of number of genes in the human genome. However, given this staggering number of proteins that
are known to exist in human body, there are only about 500 proteins so far that are known to be the targets of all the
known drugs today (Source: Science, 17th March 2000, vol. 287, pp19601964)

42.(137) Teatud juhtudel võib valkudes esineda fosforüleeritud seriinijääk. Kas seriinijäägi
fosforüleerimine toimu enne või pärast seriini lülitamist polüpeptiidahelasse?
Pärast seriini lülitamist polüpeptiidahelasse. Seriini fosforüleerimine ATP poolt kas aktiveerib või passiveerib
valku, näit. glükogeeni fosforülaasi.
