Fragment D from human fibrinogen has been crystallized. The fragment, which is composed of three disulfide-linked chains (alpha' beta' gamma' = 88,000), was generated with either plasmin or mild trypsin digestion. The crystals diffracted out to 3.5 A; the space group is P2(1), unit cell dimensions a = 108 A, b = 48 A, c = 167 A, beta = 106 degrees. Fragment D was also co-crystallized with the ligand GPRP-amide, in which case the space group is consistent with P212121, unit cell dimensions a = 476 A, b = 82 A, c = 432 A.
人纤维蛋白原的D片段已结晶。该片段由三条通过二硫键连接的链(α'β'γ' = 88,000)组成,通过纤溶酶或温和的胰蛋白酶消化产生。晶体衍射分辨率达到3.5 Å;空间群为P2(1),晶胞参数a = 108 Å,b = 48 Å,c = 167 Å,β = 106°。D片段还与配体GPRP-酰胺共结晶,此时空间群与P212121一致,晶胞参数a = 476 Å,b = 82 Å,c = 432 Å。
