Solution structure of the Alzheimer's disease amyloid beta-peptide (1-42)

The structure was published by Crescenzi, O., Tomaselli, S., Guerrini, R., et al., D'Ursi, A.M., Temussi, P.A., and Picone, D., in 2002 in a paper entitled "Solution structure of the Alzheimer amyloid beta-peptide (1-42) in an apolar microenvironment. Similarity with a virus fusion domain." (abstract).

The structure was determined using NMR spectroscopy and deposited in 2002.

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

The PDB entry contains the structure of Alzheimer's disease amyloid. This molecule has the UniProt identifier P05067 (A4_HUMAN)search. The sample contained 42 residues which is < 90% of the natural sequence. Out of 42 residues 42 were observed and are deposited in the PDB.

The molecule is most likely monomeric.
