Rampant helper syndrome: Methanogenic bacteria catalyst involved in DNA repair
Biochemistry
Methanogenic archaeans produce methane gas out of carbon dioxide and hydrogen. The underlying chemical reaction, a reduction, involves the cofactor known as deazaflavin. t has previously been found only in methanogenic bacteria, and has accordingly been considered the signature molecule for those species. Now it has been found to play a completely different role in eukaryotes.
