The Ndi1 purified from the membranes contained one FAD and showed enzymatic activities comparable with the original Ndi1 isolated from Saccharomyces cerevisiae. When extracted with Triton X-100, the isolated Ndi1 did not contain Q. The Q-bound form was easily reconstituted by incubation of the Q-free Ndi1 enzyme with ubiquinone-6. We compared the properties of Q-bound Ndi1 enzyme with those of Q-free Ndi1 enzyme, with higher activity found in the Q-bound enzyme. Although both are inhibited by low concentrations of AC0-11 (IC(50) = 0.2 microm), the inhibitory mode of AC0-11 on Q-bound Ndi1 was distinct from that of Q-free Ndi1. The bound Q was slowly released from Ndi1 by treatment with NADH or dithionite under anaerobic conditions. This release of Q was prevented when Ndi1 was kept in the reduced state by NADH. When Ndi1 was incorporated into bovine heart submitochondrial particles, the Q-bound form, but not the Q-free form, established the NADH-linked respiratory activity, which was insensitive to piericidin A but inhibited by KCN. Furthermore, Ndi1 produces H(2)O(2) as isolated regardless of the presence of bound Q, and this H(2)O(2) was eliminated when the Q-bound Ndi1, but not the Q-free Ndi1, was incorporated into submitochondrial particles. The data suggest that Ndi1 bears at least two distinct Q sites: one for bound Q and the other for catalytic Q."xsd:string |
