Nine EHPs were predicted as binding proteins. Among them, Q5NIM1 is predicted as an Ubiquinone biosynthesis accessory factor (UbiK), which is required for effective biosynthesis of ubiquinone under aerobic conditions as it forms a complex with UQ biogenesis factor UbiJ . Q5NIF3 is found to contain a lysine motif domain that is engaged with the binding process of peptidoglycan in bacteria and chitin in eukaryotes . This domain drives the signaling for distinct plant-bacteria recognition in bacterial pathogenesis . Q5NGX6 was found to be involved in iron-sulfur cluster biogenesis and to be a part of the HesB superfamily. The HesB gene is expressed only under the condition of nitrogen fixation and is found in a variety of species ranging from Haemophilus influenzae to Homo sapiens, which suggests their diversity and participation in fundamental cellular processes . Q5NG80 is predicted to contain a domain of SUF machinery involved in the biogenesis of iron-sulfur clusters. This SUF system acts as an alternative pathway to the ISC system that functions under oxidative stress and iron starvation conditions . Q5NFU0 is found to contain a Mur-like catalytic domain superfamily. Mur ligases play a critical role in the intercellular biogenesis of peptidoglycan in bacteria . The superfamily represents the central domain of all four Mur enzymes. Q5NFP5 is predicted to have a START like superfamily domain, which is involved in lipid binding in StAR, HD-ZIP and signaling proteins . StAR proteins are required for acute regulation of steroidogenesis and are expressed in the absence of hormone stimulation to drive the steroid production process . Q5NFJ0 was found to have a BamD-like outer membrane lipoprotein domain. BamD/YfiO is part of the beta-barrel assembly machinery which is required for the insertion and folding of outer membrane proteins into the outer membrane of gram-negative bacteria . As the only BAM lipoprotein required for viability, BamD contains five tetratricopeptide repeats which are suggested to be involved in the binding with other BAM components . Q5NFE0 is predicted to contain ubiquinone biosynthesis accessory factor (UbiJ), which is associated with the biosynthesis of ubiquinone under aerobic conditions . This promotes binding of hydrophobic ubiquinone biosynthetic intermediates via the SCP2 domain, which is essential for the Ubi complex stability . Q5NF39 was predicted to have a SufE-like domain, which is associated with iron-sulfur metabolism. The domain has a strong structural similarity to IscU and the sulfur-acceptor site incorporates cysteine residues to mediate iron-sulfur cluster assembly in IscU .
