1l7q Summary


Ser117Ala Mutant of Bacterial Cocaine Esterase cocE

The structure was published by Turner, J.M., Larsen, N.A., Basran, A., et al., Bruce, N.C., Wilson, I.A., and Lerner, R.A., in 2002 in a paper entitled "Biochemical characterization and structural analysis of a highly proficient cocaine esterase" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.76 Å and deposited in 2002.

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

The PDB entry contains the structure of cocaine esterase. This molecule has the UniProt identifier Q9L9D7 (COCE_RHOSM)search. The sample contained 574 residues which is 100% of the natural sequence. Out of 574 residues 570 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 is most likely monomeric.
