Asgard archaea are obligate anaerobes.
They have a Wood–Ljungdahl pathway and perform glycolysis.
Members can be autotrophs, heterotrophs, or phototrophs using heliorhodopsin.
One member, Candidatus Prometheoarchaeum syntrophicum, performs syntrophy with a sulfur-reducing proteobacteria and a methanogenic archaea.

The RuBisCO they have are not carbon-fixing, but likely used for nucleoside salvaging.
