Structure and Catalytic Mechanism of a SET Domain Protein Methyltransferase

The structure was published by Trievel, R.C., Beach, B.M., Dirk, L.M., Houtz, R.L., and Hurley, J.H., in 2002 in a paper entitled "Structure and catalytic mechanism of a SET domain protein methyltransferase." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.6 Å and deposited in 2002.

The experimental data on which the structure is based was also deposited.

This PDB entry contains multiple copies of the structure of Ribulose-1,5 biphosphate carboxylase/oxygenase large subunit N-methyltransferase.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule has more than one probable quaternary state observed. For more details see the quaternary structure page.
