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 induce chemotaxis by performing this reaction to an aspartic acid residue. This reaction is (15[1])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 the ends of polar residues such as (15[1])threonine and involves a molecule of (*) ATP. Hexokinase (10[1])performs this post-translational modification to glucose molecules. For 10 points, name this biochemical reaction that adds a group symbolized PO4-3. ■END■
