Part E - Exploring parallel B sheet structure and hydrogen bonding patterns A different segment of a B sheet found in GFP has two parallel strands. The hydrogen bonding between parallel sheets, also visible in the pdb by selecting the parallel sheet view, is shown. First, locate the N- and C-termini in this image. Next, look for a pattern in the hydrogen bonding in parallel B sheets Select the parallel sheet view in the pdb file. Complete the sentences describing the relationship between the two strands making up the sheet. Match the words in the left column to the appropriate blanks in the sentences on the right. Reset Help the carbonyl carbon of amino In the given segment showing parallel strands, there are a total of peptide chains. acid n only carbonyl carbons In a parallel B sheet, hydrogen bonds are formed between on one strand and the same amino acid on the opposite strand. the amino nitrogen of amino acid (n + 106) one four three every other amino acid only amino nitrogens two two different amino acidsPart F - Identifying parallel and antiparallel B strands A segment of the B-barrel of GFP is shown in the pdb by selecting the antiparallel sheet, parallel sheet, and antiparallel and parallel sheet view. Identify which of the following strands are in a parallel orientation and which are in an antiparallel orientation. Drag the appropriate items to their respective bins. Reset Help Antiparallel strands Parallel strands Part H - Summary of helix types Look at the position of the hydrogen bonds for the three helices shown in the pdb and match each helix with its correct identification. Drag the appropriate items to their respective bins. 31 0 helix
