Abstract

Two novel cross-linkers, disuccinimidyl tartarate (DST) and N,N'-bis(3-succinimidyloxycarbonylpropyl)tartaramide (SPT), have been synthesized. These reagents span 6 and 18 A, respectively, between functional groups and contain a vic-glycol bond which can be cleaved with periodate under mild reaction conditions. Both DST and SPT have been used to examine the near-neighbor relationships of polypeptides in ubiquinone cytochrome c reductase (complex III) from beef heart mitochondria. Among the cross-linked products resolved were pairs containing I + II, II + VI, I + V, and VI + VII. Polypeptides III and IV, a cytochrome b aproprotein, and the cytochrome c1 hemoprotein, respectively, were also resolved in several cross-linked products.
