Radiolabeling with 14C-Glutamate Describe the labeling pattern that would result from the introduction into the TCA cycle of glutamate labeled at Cy with 14C.

Expert Solution & Answer

Interpretation Introduction

Interpretation:

The labeling pattern that would result in the introduction of TCA cycle of glutamate Cγ with C14 should be described.

Concept Introduction:

The technique used to track the passage of an isotope or patterns is known as labeling pattern. TCA cycle is abbreviated as tricarboxylic acid. During this cycle, the organism especially aerobic organisms release the energy which will be a stored through the oxidation of acetyl-CoA.

Explanation of Solution

During Mitochondrial Pyruvate Transport, Glutamate maintains the TCA cycle and survival of the cell. The labeling pattern results in the same as the labeling pattern of methyl carbon of acetyl −CoA. Glutamate is converted into a-ketoglutarate and carbon a-ketoglutarate is present in the same position of methyl carbon of acetyl −CoA in the stage of the TCA cycle. In the first cycle, central carbons get labeled. In the second cycle, all the carbons will get a quarter of the label. In the first two cycles, the loss of radioactivity will not be observed. However, in later cycles, 50 % of loss of radioactivity is noticed in the level of each cycle.

You were tasked with purifying an untagged transcription factor (molecular weight 65,000Da, isoelectric point unknown) from a contaminant Protein A (molecular weight 50,000 Da, isoelectric point 5.0). You were also instructed to use the protein for crystallization studies after purification.i) In the initial purification step, which type of chromatography should you attempt? Explain your choice and specify the requirements of the buffer solution you should use. ii) Analyzing the proteins recovered from step i) using SDS-PAGE, you still observed a faint band of Protein A in addition to the transcription factor band. Given the limited time available for further purification, you must choose ONE appropriate chromatography method to maximize the chances of separating the two proteins as well as your crystallization studies. Provide a detailed explanation of your selection and the techniques/strategies you would employ to achieve this.
You were given a mixture of two proteins with different isoelectric points and molecular weights:• Protein X: pI 4.2, MW 42,000• Protein Y: pI 9.8, MW 90,000Using a Tris-glycine discontinuous native gel (pH8.3) electrophoresis system with a running gel of 12%, only a single band was observed upon protein staining after electrophoresis. Explain the observed result and discuss possible factors affecting protein migration in this system.
