This would indicate that their digestive and respiratory enzymes are quite different from those found in terrestrial life.

Grant in 1944 for research on the respiratory enzymes and the mechanism of the biological oxidation of pyruvic acid.

Cyanide ions interfere with iron-containing respiratory enzymes.

These enzymes are widely distributed in nature and represent a unique group of respiratory enzymes that catalyze the direct incorporation of molecular oxygen into various substrates.

Mutations in ATP10 induce a loss of rutamycin sensitivity in the mitochondrial ATPase, but do not affect the respiratory enzymes.

During his research, he found that some parts of organelles contained respiratory enzymes that generated anaerobic environments, meaning parts of cells could create environments with no oxygen.

FNR, an efficient respiratory oxidant induces synthesis of nitrate respiratory enzymes and simultaneously represses synthesis of enzymes for respiring the lower-potential acceptors.
