Protein

Plasma membrane-associated coenzyme Q6 reductase PGA3

Gene

PGA3

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

NADH-dependent cytochrome b5 reductase that reduces coenzyme Q6 at the plasma membrane and mediates lifespan extension by calorie restriction by shifting fermentative to respiratory metabolism, probably through modulating the NAD+/NADH ratio.2 Publications

Catalytic activityi

NADH + 2 ferricytochrome b5 = NAD+ + H+ + 2 ferrocytochrome b5.1 Publication

Cofactori

FADBy similarity

Enzyme regulationi

Inhibited by diphenylene iodonium (DPI).1 Publication
