Document Summary
Protein regulation: allosteric regulation o feedback inhibition. However with the gtp gdp it is not phosphorylation or dephosphorylation, it is simply the loss of energy with the release of a phosphate. So gdp to gtp is when you switch gtp with gdp because of. Of energy, phosphorylation is only when the phosphate. Is added to the amino acids at the hydroxyl: protein protein interactions, figure 8. 43, protein degredation o autophagy o ubiquitination. Top left to - phosphorylation, removing phosphate through hydrolysis, but it is called dephosphorylation because removing phosphate from hydroxyl by the help of protein-serine threonine kinase. Top right to left removing phosphate group from the serine with the protein serine/threonine phosphatase. Bottom right to left removing phosphate, with the help of protein tyrosine phosphatase. Bottom left to right adding a phosphate group with the help of protein tyrosine kinase. Overall: kinase adds a phosphate and phosphatase removes a phosphate. Def question on the second exam about phosphor/deposphor.
