2ntb Summary


Crystal structure of pectin methylesterase in complex with hexasaccharide V

The structure was published by Fries, M., Ihrig, J., Brocklehurst, K., Shevchik, V.E., and Pickersgill, R.W., in 2007 in a paper entitled "Molecular basis of the activity of the phytopathogen pectin methylesterase." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 2006.

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

This PDB entry contains multiple copies of the structure of Pectinesterase A.

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.
