Question

Why is methionine (AUG) removed in later processing of proteins? What is its purpose. Explain.

Answer 1

ANSWER -

methionine is used as a start codon for every protein, ie for translation every first amino acid will be methionine and at later stage it will remove.

methionine is remvoed from the later stage of processing because it is not universal that an protein will begin with the AUG, ie not every protein will begin with AUG and also it is not feasible that the protein will always begin with AUG, therefore, to maintain the versatility and universality of proteins it is removed in the later stage of protein processing.
