The protein ID number starting with Mbur represents query protein from the genome of M. burtonii. "=" means paralogous genes.

Note ¹. A homolog to MMP0400 is found in Solibacter usitatus Ellin6076 and Rubrobacter xylanophilus DSM 9941;

Note ². A homolog to MMP0607 is found in Dehalococcoides sp. CBDB1 and D. ethenogenes 195;

Note ³. A homolog to MMP1567 is found in 2 Desulfitobacterium hafniense strains (Firmicutes), and the CmuB protein from 3 species belonging to Rhizobiales of α-proteobacteria also show great similarity with MtrH;

Note ⁴. A homolog to MMP1564 is also found in Dechloromonas aromatica RCB;

Note ⁵. These 10 proteins are absent in the genome of Methanosphaera stadtmanae DSM 3091.
