Overall there is good agreement with the hydrogen bond results of the analysis with the x-ray structure results in ) and GLU 166 (1 bond in and both bonds in ), which is also present in the analysis of (figure ) and (figure ). Both also have HIS 163 which is not present computationally, and HIS 163 in the analysis of and not pointed out in but is in the binding here. There is a weak SER 144 bond in and there is also here. PHE 140 is in the computational binding model but not either of the these papers. GLN 189 is not but THR 190 is there and weak .
