Q5. The structure shown below is a protein Richardson representation. Key components of the structure are labeled with the numbers 1 through to 5 Answer A, B, and C 5 A) What is the major type of secondary structure shown in the representation? (2 marks) B) Which label (1, 2,3,4, or 5) shows the N ter minus of the protein 1 mark) What parts of a protein structure would you expect to be most conserved during the however your answer should be applicable to any protein structure. (3 marks) Question total-6 marks) C) course of evolution? You may refer to the structure shown here in your answer

Explanation / Answer

Ans a) The major secondary structure that we can see in this protein are the alpha helix and beta sheet. They are held together with help of hydrogen bonds. The beta sheets are the major structure that we see here where the beta strands are connected by at least two or three hydrogen bonds in the background. The beta strand is usually 3 to 10 amino acid long.

Ans b) The number 2 represents the N- terminal or the amino terminal. It is aligned with the C-terminal of the adjacent chain.

Ans c) The part of the proteins which carry the sequences that is responsible for the function of the protein is the most conserved part of the protein.
