2ace Summary


PDB entry 2ace (supersedes 1ace)


There is a Quite Interesting Protein Structure article for this entry.

The structure was published by Raves, M.L., Harel, M., Pang, Y.-P., Silman, I., Kozikowski, A.P., and Sussman, J.L., in 1997 in a paper entitled "Structure of acetylcholinesterase complexed with the nootropic alkaloid, (-)-huperzine A." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.5 Å and deposited in 1996.

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

The PDB entry contains the structure of ACETYLCHOLINESTERASE. This molecule has the UniProt identifier P04058 (ACES_TORCA)search. The sample contained 537 residues which is 95% of the natural sequence. Out of 537 residues 520 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.
