    Protein Summary

       

    Gene XCC1541 from Xanthomonas campestris encodes the NP_636912 protein from the COG2945 group (e-val=1e-4). Its genomic neighbor, XCC1542, is annotated as acetyltransferase.

    pre-SCOP classifies 2qjw in the alpha/beta class, alpha/beta hydrolases superfamily, acetyl xylan esterase-like family. According to DALI, 2qjw shows significant structural similarity to PDB entries 2i3d (1.8 Å rmsd, 158 aligned residues, 10% sequence id; Z=21), 1uxo (2.3 Å rmsd, 155 aligned residues, 14% sequence id; Z=17) and 3bdv (2.3 Å, 153 aligned residues, 20% seq.id.; Z=18). Similar values are obtained for lipases (PDB ids: 3d2c, 1t2n, 1t4m and 2qxt, rmsd 2.2 Å, 147 aligned residues, 11% sequence id; Z=17) and for an a/b hydrolase (PDB id: 2fuk, rmsd 2.0 Å, 157 aligned residues, 18% sequence id; Z=20). 1uxo structure has been described as an a/b hydrolase (1).

        

    To do: check if 2qjw ligands (P6G or TLA) might be mimetics of biological substrate.
