Three N-terminal residues are present in the working sequence (168Ala, 169Ser, 170Val) but have not been modelled. There were weak electron densities suggesting that GLN892 and HIS893 might be present. This information provides a clue in analyzing which direction the last nine C-terminal residues go.
