From: The [FeFe] hydrogenase of Nyctotherus ovalis has a chimeric origin
Phylogenetic tree of the 51 kDa-like module of the hydrogenase of N. ovalis, mitochondrial complex I 51 kDa subunits, bacterial NuoF, and bacterial hydrogenase subunits. See methods for how the tree was calculated. H: N. ovalis hydrogenase, M: ciliate mitochondrial. Only bootstraps ≥ 50 are indicated in the tree. Box 1 marks the fused modules (with the exception of Nitrosospira multiformis), Box 2 the non-fused modules of mitochondrial and alpha-proteobacterial origin. All bacteria in Box 1 (with the exception of Nitrosospira multiformis) have a [NiFe] hydrogenase.
