A series of auxotrophic mutants were isolated in Neurospora. Examination of fungi containing these mutations revealed that they grew on minimal medium to which various compounds (A, B, C, D) were added; growth responses to each of the four compounds are presented in the following table. Give the order of compounds A, B, C, and D in a biochemical pathway. Outline a biochemical pathway that includes these four compounds and indicate which step in the pathway is affected by each of the mutations. Compound Mutation number А в С A D 134 276 987 773 772 146 333 123 + + I +
The pathway for cystiene synthesis in E.coli involves five precursor compounds, compound A-E. The requirements for each of the autotrophs are summarized in the table below. Use the data, define the biosynthetic pathway. Draw the pathway for cysteine synthesis. Fill in the blanks with A-E compounds as appropriate and then label the arrows with the auxotrophs C1-C8 that are unable to complete that step. There are may be more than one quxotroph that is defective at a particular step. that is - on C4 in D
A number of auxotrophic mutant strains were isolated from wild-type haploid Neurospora crassa. These strains responded to the addition of certain nutritional supplements to minimal culture medium either by growth (+) or no growth (0) The data from this experiment are presented in the table below. Diagram a biochemical pathway, complete with positions of intermediates, that is consistent with the data. Indicate where in the pathway each mutant strain is blocked.
Azathioprine is an immunosuppressant drug used in kidney transplants. In vivo, azathioprine is metabolized to the hypoxanthine analog 6- mercaptopurine, which is then converted into 6-mercaptopurine ribose monophosphate, the active form of the drug. 6- Mercaptopurine ribose monophosphate also inhibits de novo purine synthesis, reducing uric acid levels in the blood and urine. However, when administered to Lesch – Nyhan patients, there was no effect on uric acid levels. Explain why this is the case.

You are studying a biochemical pathway and isolate Neurospora mutants I, II, and III.Mutant I can grow if you supplement the medium with Z.Mutant II can grow if you supplement the medium with X, Y, or Z.Mutant III can grow if you supplement the medium with X and Z, but not with Y. Draw a biochemical pathway that shows the correct order for compounds X, Y, and Z and for the enzymes that each mutant is defective for.

A variety of organic chelating ligands have been synthesized to tightly coordinate radioactive metal cations to identify and treat malig- nancies by coupling the metal complex to a polypeptide linker attached to a monoclonal antibody that binds specifically to a cell surface re- ceptor. One such metal complex is illustrated in the diagram on the right. The radioactive Cu-64 cation is tightly coordinated by the che- lating ligand that is, in turn, conjugated to a peptide linker attached to a monoclonal antibody. (The antibody is not shown in this diagram.) When coupled to a specifically designed monoclonal antibody, the complex binds specifically to somatostatin receptors that are ex- pressed on the surface of neuroendocrine tumors. Subsequently the entire complex with the receptor is internalized, i.e., passed into the cytoplasm, where the radioactive metal cation kills the malignant cell. 1.
