Draw the structure of the anti-HIV drug AZT (zidovudine), which stops retro-viral DNAsynthesis. When AZT is taken up by cells, it is converted to AZT triphosphate. Explain how thiscompound could interfere with DNA synthesis
In the mevalonate pathway, three acetyl-CoA are combined to give a C5 product, IPP.A. Write out a 5-step general acid/general base mechanism to explain how HMG-CoA isformed from 3 acetyl-CoA (Note: we are leaving out some details. The enzyme HMG-CoA actuallyuses its Cys residues to accept acetyl groups from 2 acetyl-CoA, making new thioesters and liberatingCoASH) B. Two NADPH and two H+ are required to form mevalonic acid from HMG-CoA. Circle the Hatoms that came from NADPH, and put a square around any H atoms that came from H+.C. Three ATP are used to convert mevalonic acid to IPP. Explain the role of each ATP molecule
