Structure of the Histone H3-Asf1 Chaperone Interaction

The structure was published by Antczak, A.J., Tsubota, T., Kaufman, P.D., and Berger, J.M., in 2006 in a paper entitled "Structure of the yeast histone H3-ASF1 interaction: implications for chaperone mechanism, species-specific interactions, and epigenetics." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 Å and deposited in 2006.

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

The PDB entry contains the structure of Anti-silencing protein 1 and Histone H3 Chimera. This molecule has the UniProt identifier P32447 (ASF1_YEAST)search. The sample contained 179 residues which is < 90% of the natural sequence. Out of 179 residues 167 were observed and are deposited in the PDB.

The molecule is most likely monomeric.
