HUMAN ACETYLCHOLINESTERASE COMPLEXED WITH FASCICULIN-II, GLYCOSYLATED PROTEIN

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

The structure was published by Kryger, G., Harel, M., Giles, K., et al., Shafferman, A., Silman, I., and Sussman, J.L., in 2000 in a paper entitled "Structures of recombinant native and E202Q mutant human acetylcholinesterase complexed with the snake-venom toxin fasciculin-II." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.76 Å and deposited in 1999.

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

This PDB entry contains a complex of 2 biomacromolecules, namely ACETYLCHOLINESTERASE and FASCICULIN-2.

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.
