Báo cáo khoa học: Reconstitution of coupled fumarate respiration in liposomes by incorporating the electron transport enzymes isolated from Wolinella succinogenes
Hydrogenase and fumarate reductase isolated fromWoli-nella succinogeneswere incorporated into liposomes con-taining menaquinone. The two enzymes were found to be
oriented solely to the outside of the resulting proteolipo-somes. The proteoliposomes catalyzed fumarate reduction
by H2
which generated an electrical proton potential (Dw
0.19 V, negative inside) in the same direction as that gen-erated by fumarate respiration in cells ofW. succinogenes.
