    Protein Summary

    The TM0488 gene from Thermotoga maritima encodes a N5-glutamine methyltransferase, HemK (EC 2.1.1.-)

    (PF01575, COG2890). The TM0488 structure adopts an S-adenosyl-L-methionine dependent methyltransferase fold and shows strong structural similarity (main-chain rmsd 0.4 Å over 266 residues) with N5-glutamine methyltransferase HemK from Thermotoga maritima (PDB id: 2nv8, 1sg9). See Schubert 2003 for more details on the structure and mechanism.
