    Protein Summary

    The gene TM0957 from Thermotoga maritima encodes the NP_228765 protein, a predicted periplasmic lipoprotein from the DUF2291 group (PF10054).  

    A fold type search indicates that the 2f4i structure belongs to the OB (oligonucleotide/oligosaccharide binding)-fold (SCOP50198 ). DALI weak top hit is with the putative nucleic acid binding lipoprotein 3f1z (Z=7).

    The OB-fold domains have been observed in four different proteins which bind oligonucleotides or oligosaccharides: nuclease, anticodon binding domain of Asp-tRNA synthetase and B-subunits of heat-labile enterotoxin and verotoxin-1 [Ref].
