Structure of eukaryotic translation termination complex methyltransferase Mtq2-Trm112

The structure was published by Liger, D., Mora, L., Lazar, N., et al., van Tilbeurgh, H., Heurgue-Hamard, V., and Graille, M., in 2011 in a paper entitled "Mechanism of activation of methyltransferases involved in translation by the Trm112 'hub' protein" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.997 Å and deposited in 2011.

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

This PDB entry contains a complex of 2 biomacromolecules, namely Putative uncharacterized protein ECU08_1170 and N6 adenine specific DNA methylase.

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 most likely forms heterodimers.
