    Protein Summary

    The DSY2733 gene translates into the YP_518966.1 amino acid sequence which corresponds to a 113 residues long protein belonging to the Cupin-2 family, characterized by a ~70 aa sequence containing the conserved  motifs PGxxxxxHxH, and HxxxN, weakly present here (PF07883). Analysis of the gene context detects with a 0.785 score the putative translocase protein YP_518968.


    SCOP classifies 2ozj inside the all-beta class, superfamily RmlC-like cupins, family TM1287-like. FFAS (score -52) and HHpred (P-val=1.7e-39) provide a top hit with 1yhf; Dali (Z-scr=17) and FATCAT (P-val=1.5e-14) corroborate finding. A close second hit is 3fjs. SSM finds high secondary structure matching (63%) with 2f4p, a cupin-like protein.
