Phylogenetic trees for some GOPs. Phylogenetic trees constructed by maximum-likelihood algorithm for a acetate kinase AckA, involved in acetoclastic methanogenesis, and b uncharacterized alpha/beta hydrolase (PF12695) . Methanosarcina spp. are shown in red, other Methanosarcinaceae in orange, Firmicutes in light green, Actinobacteria in blue, Synergistetes in brown, Thermotoga in dark-purple, Proteobacteria in purple, Dictyoglomi in yellow, Cyanobacteria in emerald, and Aquificae in grey. Other archaea are shown in dark blue
