Anti-cancer drugs that disable enzymes that cause this chemical change include “type-1.5” inhibitors exemplified by vemurafenib (vem-yew-RAFF-in-ib). Two-component systems consist of a response regulator and an enzyme that causes this chemical change, which unusually acts specifically on histidine. This change is caused by the enzyme Aurora B, which is activated during (*) mitosis as part of this change’s namesake cascade. (10[1])Glycogen is broken down by an enzyme that causes this change to a terminal glucose. In proteins, this change normally only occurs to tyrosine, (10[1])serine, and threonine. Enzymes that cause this change to the substrate, such as the JAK and MAPK families, are called (10[2])kinases. For 10 points, name this chemical change that converts ADP to ATP. ■END■
