Abstract
⺠O2-tolerant hydrogenases harbor a novel [FeS] cofactor with 6 cysteine (6C) coordination. ⺠Through genomic screenings we map the 6C trait onto the most recent phylogenetic tree. ⺠Structural/functional characteristics correlate with the planet's geochemical history. ⺠6C hydrogenases are omnipresent in recent microaerophilic and aerobic bacterial phyla. ⺠A link between 6C enzymes and increasing oxidative atmospheric conditions is proposed.
