The structure shown below is a protein Richardson representation. Key components

Question

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. A) What is the major type of secondary structure shown in the representation? B) Which label (1, 2, 3, 4, or 5) shows the N terminus of the protein? C) What parts of a protein structure would you expect to be most conserved during the course of evolution? You may refer to the structure shown here in your answer, however your answer should be applicable to any protein structure.

Explanation / Answer

b) Label 2 is shows N- terminous of protein in this structure because the protein structure starts from direction of arrows so here it starts from label 2.

A) beta strands is a major secondary structure present in this presentation. It represent by arrows with thickness, about one quater thick as they are wide shows direction and twist of the strand from amino to carboxyl terminal.

C) domain is most conserved during course of evolution, here beta domain is formed that is conserved during the course of evolution.
