Question 1. 1.1 Two sections of a polypeptide backbone from a large protein are shown as follows: amino acids 8-11 and amino acids 40-43. Determine if this is a parallel or anti-parallel b-sheet. Label the N and C termini of each polypeptide and label the R groups according to their number. Draw hydrogen bonds that would stabilize this beta-sheet. R A 1 R o R - 2 N poze w "CH 11 R R R ozu R 1 CH N C N CH 1 w C CA R 0 N 1.2 You compare this protein across different species and find the following consensus sequence: 8-MXFX .... 40-YXLX Where M, F, Y, and L are conserved amino acids and where X is any amino acid other than proline (so NOT conserved). Come up with a hypothesis that explains this pattern of conservation
