    Protein Summary

    Gene SMc00288 (NP_385823) from legume symbiont bacteria Sinorhizobium meliloti 1021 encodes a predicted secreted protein with 163 residues. The 135 amino acid construct, with a removed (predicted) signaling peptide was solved by JCSG.   This protein is a second member of PFAM family PF02643 (DUF192,

    reference to undefined name 'note' Exception of type 'MindTouch.Deki.Script.Runtime.DekiScriptUndefinedNameException' was thrown. (click for details)
    ), solved by JCSG, the first being  being 3m7a. DUF192 is a large (>500 members) and broadly distributed family of bacterial proteins, present mostly in environmental bacteria and metagenomes (distant homologs are also present in several Plasmodium species).

     

    Dali search and SSM alignment find only its homolog (

    reference to undefined name 'note' Exception of type 'MindTouch.Deki.Script.Runtime.DekiScriptUndefinedNameException' was thrown. (click for details)
    ), solved previously by JCSG and annotated as having unknown function. Distant structural similarity and genome context and gene fusion analysis suggests possible involvement in sugar metabolism as an auxiliary substrate binding domain, see the discussion on the TOPSAN 3m7a page http://www.topsan.org/Proteins/JCSG/3m7a
