Question

One single polypeptide chain  (120 amino acid residues) is produced for protein A in prokaryotic cell. N-terminal amino acid is alanine in the chain of this protein. How many moles of ATP and GTP will be in use for this polypeptide chain synthesis? What post-translational modifications may be for this protein?

Expert Solution
Step 1

A polypeptide chain is a linear or cyclic  compounds which have amino acids as the building units of this chain,

If the number of amino acids in the chain are less and limited then it is called an enzyme which are formed according to the need of organs and different body parts.

If the number of amino acids is more or many then it is called a protein which are also formed according to the different needs and different cycles of the body. 

ATP : Adenosine Triphosphate

GTP : Guanosine Triphosphate
