All significant blast hits for these proteins are from the indicated (marked by *) Bacteroidetes and Chlorobi species. For the protein PG0081, a homolog is also present in Fibrobacter succinogenes subsp. succinogenes S85 (identified by blast search against the partial sequence). The blank space indicates that no hit showing significant similarity was detected at the present time.
