Improved crystal structure of magnesium transporter MgtE

The structure was published by Hattori, M., Iwase, N., Furuya, N., et al., Ito, K., Maturana, A., and Nureki, O., in 2009 in a paper entitled "Mg(2+)-dependent gating of bacterial MgtE channel underlies Mg(2+) homeostasis" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.94 Å and deposited in 2009.

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

This PDB entry contains multiple copies of the structure of Mg2+ transporter MgtE.

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 homodimers.
