The Simultaneous Oxidation and Phosphorylation of Glyceraldehyde 3-Phosphate Forms a Highly

question 46

Multiple Choice

The simultaneous oxidation and phosphorylation of glyceraldehyde 3-phosphate forms a highly reactive covalent thioester bond between a cysteine side chain (reactive group ?SH) on the enzyme (glyceraldehyde 3-phosphate dehydrogenase) and the oxidized intermediate (see the arrow in Figure 13-23A) .If the enzyme had a serine (reactive group ?OH) instead of a cysteine at this position, which could form only a much lower energy bond to the oxidized substrate (see the arrow in Figure 13-23B) , how might this new enzyme act? (A)


(B)

Figure 13-23

• C)It would phosphorylate the substrate on the 2 position instead of the 1 position.
• D)It would behave just like the normal enzyme.
