This will show us all the atoms (except for the hydrogens) coloured by the 'CPK' colour scheme we talked about in lectures - blue for nitrogen atoms, red for oxygen atoms, grey for carbon atoms and yellow for sulfur atoms. Pretty hard to see what's going on, isn't it? | <scene name='User:J._Shaun_Lott/BIOSCI_203/All_atoms_view/1'>here</scene> for an 'all atoms' view of the protein.

We can simplify things by just showing a cartoon that traces the path of the amino acid backbone; α-helices are shown as coils, and β-strands as arrows pointing in the direction of the C-terminus of the protein. <scene name='User:J._Shaun_Lott/BIOSCI_203/Ss_rainbow/ | We can simplify things by just showing a cartoon that traces the path of the amino acid backbone; α-helices are shown as coils, and β-strands as arrows pointing in the direction of the C-terminus of the protein. <scene name='User:J._Shaun_Lott/BIOSCI_203/Ss_rainbow/3'>Here</scene> is a version with the cartoon coloured from blue at the N-terminus to red at the C-terminus. <scene name='User:J._Shaun_Lott/BIOSCI_203/Ss_elements/2'>Here </scene>is a version with the β-strands coloured yellow and the α-helices coloured pink. | ||
