Thermodynamics of Binding of 2-methoxy-3-isopropylpyrazine and 2-methoxy-3-isobutylpyrazine to the Major Urinary Protein

The structure was published by Bingham, R.J., Findlay, J.B.C., Hsieh, S.-Y., et al., Turnbull, W.B., Bodenhausen, G., and Homans, S.W., in 2004 in a paper entitled "Thermodynamics of Binding of 2-Methoxy-3-isopropylpyrazine and 2-Methoxy-3-isobutylpyrazine to the Major Urinary Protein." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.7 Å and deposited in 2003.

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

The PDB entry contains the structure of Major Urinary Protein. This molecule has the UniProt identifier P11588 (MUP1_MOUSE)search. The sample contained 174 residues which is 90% of the natural sequence. Out of 174 residues 157 were observed and are deposited in the PDB.

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.
