1.3.5.1 | fumarate + 2,3-dimethyl-1,4-naphthohydroquinone |
- |
1.3.5.1 | fumarate + a menaquinol |
the enzyme is involved in anaerobic metabolism |
1.3.5.1 | fumarate + menaquinol |
fumarate reductase acts as part of an anaerobic respiratory chain |
1.3.5.1 | fumarate + menaquinol |
the enzyme catalyzes the terminal step of the phosphorylative electron transport |
1.3.5.1 | fumarate + reduced acceptor |
FrdCAB functions in vivo as both the fumarate reductase and the succinate dehydrogenase, with an apparent energetic cost when catalyzing succinate oxidation |
1.3.5.1 | fumarate + reduced acceptor |
the obligate autotroph requires fumarate reductase activity if it performs CO2 fixation via a reductive citric acid cycle |
1.3.5.1 | more |
the enzyme has the function to oxidize succinate to fumarate, as part of the Krebs' cycle and directly couples this to the reduction of quinone in the membrane, quinol is then oxidized by the respiratory chain |
1.3.5.1 | more |
membrane-bound enzyme of the citric acid cycle and the respiratory chain |
1.3.5.1 | more |
complex II of adult organism muscle exhibits high fumarate reductase activity and plays a key role in anaerobic electron-transport during adaptation to their microaerobic habitat, in contrast larval complex II shows a much lower fumarate reductase activity than the adult enzyme and functions as succinate dehydrogenase in aerobic respiration |
1.3.5.1 | more |
complex II from mitochondria of the adult parasitic nematode exhibits a high fumarate reductase activity and plays a key role in the anaerobic electron transport observed in these organelles |
