Three accessory proteins were predicted, of which Q5NIL9 is found to contain ribosome maturation factor (RimP), which induces maturation of the 30S ribosomal subunit and is essential for the effective development of translationally competent ribosomes . Q5NGE5 is predicted to contain an MTH-938-like superfamily domain. MTH938 is a hypothetical protein encoded by Methanobacterium thermoautotrophicum and the superfamily contains NDUFAF3 essential factor for the assembly of mitochondrial NADH: ubiquinone oxidoreductase complex . Q5NG32 is found to have an organic solvent tolerance-like domain, which is found in a number of bacterial proteins, including the lipopolysaccharide assembly protein lptD .
