CRYSTAL STRUCTURE OF THE QUINOPROTEIN METHYLAMINE DEHYDROGENASE FROM PARACOCCUS DENITRIFICANS AT 1.75 ANGSTROMS

The structure was published by Chen, L., Doi, M., Durley, R.C., et al., Lidstrom, M.E., Davidson, V.L., and Mathews, F.S., in 1998 in a paper entitled "Refined crystal structure of methylamine dehydrogenase from Paracoccus denitrificans at 1.75 A resolution." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.75 Å and deposited in 1993.

The experimental data on which the structure is based was not deposited.

This PDB entry contains a complex of 2 biomacromolecules, namely METHYLAMINE DEHYDROGENASE (HEAVY SUBUNIT) and METHYLAMINE DEHYDROGENASE (LIGHT SUBUNIT).

The molecule most likely forms heterotetramers.
