The R domain of the CFTR protein is a target for this reaction. Upon substrate binding, insulin receptor proteins perform this reaction on themselves. Bacteria can (15[1])induce chemotaxis by performing this reaction to an aspartic acid (15[1])residue. This (15[1])reaction is inhibited by vanadate ions, which are commonly used in cell lysis buffers. Glycogen synthase is deactivated by multiple instances of this reaction on serine (15[1])residues. This reaction commonly occurs at (15[1])the ends of polar residues such as threonine and involves a molecule of (*) ATP. Hexokinase performs this (10[1])post-translational modification to glucose molecules. For 10 points, name this biochemical reaction that adds a group symbolized PO4-3. ■END■
