In MHC Class I (mouse and human) Q226 is part of the binding site for CD8[1]. Regarding the alpha chain (A) in human MHC 1akj, the authors state:
A flexible loop of the alpha3 domain (residues 223-229) is clamped between the complementarity-determining region (CDR)-like loops of the two CD8 subunits in the classic manner of an antibody-antigen interaction ....
Hydrogen bonds between CD8 and the alpha chain of HLA-A2 that involve this loop are (from Table 2[1]):
CD8:D T30.OG1 : T225.O HLA-A2:A 2.7 Å CD8:E S34.OG : Q226.NE2 3.0 CD8:D S100.O : Q226.NE2 3.0 CD8:D S100.OG : Q226.O 2.7 CD8:E Y51.OH : D227.OD2 3.0 CD8:D N99.OD1 : L230.N 3.0 CD8:D N99.ND2 : L230.O 3.4 CD8:D S27.OG1 : E232.OE1 2.7
