3bta Summary



The structure was published by Lacy, D.B., Tepp, W., Cohen, A.C., DasGupta, B.R., and Stevens, R.C., in 1998 in a paper entitled "Crystal structure of botulinum neurotoxin type A and implications for toxicity." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.2 Å and deposited in 1998.

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

The PDB entry contains the structure of PROTEIN (BOTULINUM NEUROTOXIN TYPE A). This molecule has the UniProt identifier P10845 (BXA1_CLOBO)search. The sample contained 1295 residues which is 100% of the natural sequence. Out of 1295 residues 1276 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.
