This family of proteins with unknown function appears to be restricted to Mycoplasma and Ruminococcus spp. The structure of Uncharacterized protein MG376 homolog from Mycoplasma pneumoniae shows an OB fold with six beta-strands and three loops forming a beta-barrel that is capped by one alpha-helix [1]. Its specific function is still unknown.	Domain
