Chapter 31, Problem 2P
Interpretation Introduction

Interpretation:

The concentration of lac repressor should be calculated.

The free or bound state of lac repressor with DNA should be determined.

Concept introduction:

E. Coli contains of lac operon, which is involved in lactose metabolism. It can be expressed in the presence of lactose and absence of glucose. The two regulators of lac operons are the lac repressor and the CAP. The function of these two regulators is to turn ‘on’ and ‘off’ the operon in response to glucose and lactose.

You’ve isolated a protein and determined that the Native molecular weight of the holoenzyme is 160 kD using size exclusion chromatography. Analysis of this protein using SDS-PAGE revealed 2 bands, one at 100 kD and one at 30 kD.  The enzyme was found to be 0.829% NAD (by weight). What further can be said regarding the structure of the polypeptide?
What is the formation of glycosylated hemoglobin (the basis for the HbA1c test)? Can you describe it?
Please analze the gel electrophoresis column of the VRK1 kinase (MW: 39.71 kDa).  Also use a ruler to measure the length of the column in centimeters and calculate the MW of each band observed.
