Fig. 4: Tes homologs are found in diverse archaeal and bacterial phyla.
From: Identification of a protein responsible for the synthesis of archaeal membrane-spanning GDGT lipids
These data were generated through BLASTP searches of Tes homologs (e-value < 1e−50, identity > 20%) in the NCBI database and searching published studies demonstrating GDGT production from pure cultures3,5,9,10,36,69,70,71. At least one strain or one genome in the phylum, class or order containing the Tes homolog and GDGTs (at least GDGT-0) is marked with a black circle. Otherwise, archaea or bacteria without any Tes homolog or GDGTs are marked with white circles. Uncultured archaeal strains or with cultured strains not yet tested for GDGT production, are marked with gray circles. Only one putative Tes homolog (e-value = 6e−53, identity = 28%) was identified from 231 MG-II MAGs (*). Phylogenetic lineages of archaea and bacteria are modified from references31,72,73. Proteobacteria and acidobacteria are divided into class level and order level, respectively. Terrabacteria, FCB (Fibrobacteres-Chlorobi-Bacteroidetes), PVC (Planctomycetes-Verrucomicrobia-Chlamydiae) and CPR (Candidate Phyla Radiation) are bacterial superphyla72,73 and only several phyla are shown in each group. Bacterial phyla that do not belong to these groups are assigned “Other” in the figure. Details and references are listed in Supplementary Table 2.
