Estimate the molecular weight the identical subunits in the picture. Use the value 110 Da as the average molecular weight of an amino acid.
Homework Answers
If you carefully notice, the picture shown here is of a protein with two identical subunit and EACH subunit consist of two alpha helices of equal turn joined together. Each alpha helices has 7 turns. As a rule of thumb, one turn of an alpha helix contains 3.6 aminoacid residues. Therefore,
CALCULATION:
Molecular weight of each subunit is= 2 (# of helices) x 7 (# of turns per helices)x 3.6 (# of aminoacids per turn) x 110 (avg. molecular weight of an aminoacid) =5544 Da or 5.54 kDa

The molecular weight of the A and B chains of the E. coli enzyme, tryptophan synthase, are 29,500 and 49,500 Daltons, respectively. The size of the entire quaternary enzyme complexes 159,000 Daltons. If the average molecular weight of each amino acids is 110, then how many amino acids are present in the A chain? (Enter a number and round to the nearest integer.)

Assume you were given a mixture consisting of one molecule each of all possible sequences of a smallish protein of molecular weight 4800 daltons. If the average molecular weight of an amino acid is, say, 120 daltons, how much would the sample weigh? How big a container would you need to hold it? What does this calculation tell you about the fraction of possible proteins that are currently in use by living organisms (the average molecular weight of proteins is...

5. A native protein has a molecular weight of 150,000 Da. Denaturing SDS electrophoresis results in two bands with molecular weights of approximately 53,000 and 23,000 Da. What arrangement of polypeptide chains in the native protein would best explain these results? 2. If two proteins have the same molecular weight, are they necessarily the same protein? Can you definitely assign the identity of a protein based on its molecular weight? Why or why not?
