    Protein Summary

    The Jann_0674 gene from Jannaschia sp. ccs1 encodes a member of the thioesterase superfamily (PF03061, COG0824) that adopts a thioesterase/thiol ester dehydrase-isomerase fold. Remote homology and structural similarity both suggest the protein might function as an acyl-ACP thioesterase (HHPred P-value 1.2E-21 with PF01643 over residues 13-149; DALI Z-score 11.5, rmsd 1.9 Å over 102 residues, identity 16% with PDB id 2GVH).


    To do: identify acyl-CoA binding site, pathway


    Has some sequence similarity to acyl-ACP thioesterase (Pfam01643).
