ALPHA-SPECTRIN SRC HOMOLOGY 3 DOMAIN, CIRCULAR PERMUTANT, CUT AT S19-P20

The structure was published by Viguera, A.R., Blanco, F.J., and Serrano, L., in 1995 in a paper entitled "The order of secondary structure elements does not determine the structure of a protein but does affect its folding kinetics." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.02 Å and deposited in 1996.

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

The PDB entry contains the structure of ALPHA-SPECTRIN. This molecule has the UniProt identifier P07751 (SPTN1_CHICK)search. The sample contained 63 residues which is < 90% of the natural sequence. Out of 63 residues 60 were observed and are deposited in the PDB.

The molecule is most likely monomeric.
