The structures, functions and anticoagulant mechanisms of anticoagulation factors ACF I and ACF II from the venom of Agkistrodon acutus have been investigated. Both ACF I and ACF II form a 1:1 complex with activated coagulation factor X in a Calcium ion-dependent fashion which prevents the interaction of FXa with other proteins in the coagulation process, therefore ACF I and ACF II have marked anticoagulant activity.

The five prosthetic groups (FAD, [2Fe-2S], [4Fe-4S], [3Fe-4S] and heme group) required for electron transfer from succinate to ubiquinone were unambiguously assigned into the electron density map. Besides, we find there are some electron densities around the Qp pocket at the matrix side and we believe it represents the head structure of ubiquinone, which is proved by the inhibitor bound structure that 2-TTFA just locating at the Qp site. At the same time, we find there is the second 2-TTFA binding site, locating the inter-membrane side. This finding will change our knowledge about the electron transfer inside Complex II and the ubiquinone transfer between Complex II and Complex III, and endow a new role of Complex II in electron transfer chain.
