    Protein Summary

    The Mfla_0564 gene from Methylobacillus flagellatus kt encodes the YP_544675 protein, a nuclear transport factor 2 (NTF2) domain (PF02136). HHPred gives strong hits with the association domain of calcium/calmodulin dependent protein kinase II (PF08332, P-value 3.8E-12 over residues 9-117) and scytalone dehydratase (PF02982, EC, P-value 6.2E-11 over residues 4-116). PSI-BLAST provides a hit with the C-terminal region of dehydrogenase ZP_05519550 (e-val=9e-6; seq. id. 32%; gaps 3%).

    According to pre-SCOP, the 3duk structure adopts a cystatin-like fold inside the NTF2-like superfamily, ketosteroid isomerase-like family. DALI top hits are with NTF2-like proteins 3blz (Z=20), 3fka (Z=17) and the ketosteroid isomerase-like protein 3d9r (Z=14).


    To do: compare presence/absence of catalytic residues to determine whether this protein could be a scytalone dehydratase.
