Prоtein phоsphоrylаtion (аdding а phosphate group) is an important regulation of protein activity and function. Upon phosphorylation, a phosphate moiety is covalently attached to a hydroxyl (-OH) group of any of the three amino acids: Tyrosine (Y), Threonine (T) or Serine (S), which are the only 3 amino acids with a side chain containing hydroxyl. To become active, a Map kinase has to undergo phosphorylation of its catalytic domain on amino acids 183 and 185 according to the primary structure. To create a catalytically inactive Map kinase - a kinase dead mutant - the most likely substitution within its active domain would be (Give detailed explanation for your answer too): A. A183T185 B. Y183A185 C. G183A185 D. S183Y185
