摘要
Long-term nonprogression during simian immunodeficiency virus (SIV) infection has been strongly associated with the major histocompatibility complex (MHC) class I allele Mamu-B*17. Here, a complex of rhesus macaque Mamu-B*17 with rhesus macaque β2-microglobulin (β2m) and an immunodominant peptide (SIVmac239 Env241-251; LRCNDTNYSGF; Env LF11) derived from the SIV Env protein was crystallized by the hanging-drop method using PEG 3350 as a precipitating agent. The crystals belonged to the primitive monoclinic space group P2, with unit-cell parameters a = 68.3, b = 45.0, c = 81.5 à , β = 96.5°. Assuming the presence of one molecule in the asymmetric unit, the Matthews coefficient and solvent content were calculated to be 2.96 à (3) Da(-1) and 58.5%, respectively.
