NiFe hydrogenase enzymes encoded by CPR bacteria. a Inset of the unrooted large subunit hydrogenase tree showing putative Group 3b hydrogenases across the CPR, along with the presence/absence of HMM hits corresponding to other subunits. b Genomic context for hydrogenase gene clusters, where position 0 corresponds to the location of the ORF encoding the large subunit of the NiFe hydrogenase. Only protein families on the same strand as the large subunit are represented in the plots, whereas genome diagrams below the charts include all proximal families regardless of strand orientation. c Inset of large subunit tree within Group 4 hydrogenases. Ehr, energy-converting hydrogenase-related complexes. Scale bars represent the average number of substitutions per site
