Activated carriers participate in carbohydrate, peptidoglycan, lipid, and LPS synthesis. Briefly describe these carriers and their roles. Are there any features common to all the carriers? Explain your answer.

. The mechanism for lysozyme cleavage of its polysaccharide substrate requires Glu35 in its nonionized form, whereas the nearby Asp52 must be ionized (see the figure below). The pK values for the side-chain carboxyl groups on the two amino acids in solution are virtually identical. a) How can one carboxyl group be charged and the other uncharged in the active site of lysozyme? b) The pH optimum for lysozyme is about 5. Why do you suppose that the activity decreases above and below this optimum? Glu3s NAG Asp52 0-H Glu35 -C Asp52 tri-NAG NAG
In acute lymphoblastic leukemia, the cancerous white blood cells typically lack the enzyme asparagine synthetase. Why is the administration of asparaginase an eff ective therapy for this type of cancer?
4. Cells sense internal amino acid levels to couple their metabolic state with their gene expres- sion programs. One key regulatory switch that amino acid levels control is expression of the genes required for ribosome biogenesis – all the proteins and RNA molecules that required to generate the small and large ribosomal subunits. Ribosome biogenesis is one of the most resource-intensive pro- cesses in proliferating cells. In order to couple ri- bosome biogenesis – which entails high level syn- thesis of hundreds of proteins – with the availabil- ity of amino acid precursors required to make those proteins, cells evolved a signaling network that converges on a key protein complex in the cell known as MTOR complex 1 (MTORC1). The net result of the signaling network shown in the diagram is that mTORC1 is ultimately activated by the presence of leucine and arginine in the cell (the blunt arrows represent inhibitory interactions; the details are not important here). When MTORC1 is active,…
