2pv3 Summary


Crystallographic Structure of SurA fragment lacking the second peptidyl-prolyl isomerase domain complexed with peptide NFTLKFWDIFRK

The structure was published by Xu, X., Wang, S., Hu, Y.X., and McKay, D.B., in 2007 in a paper entitled "The Periplasmic Bacterial Molecular Chaperone SurA Adapts its Structure to Bind Peptides in Different Conformations to Assert a Sequence Preference for Aromatic Residues." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.39 Å and deposited in 2007.

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

This PDB entry contains a complex of 2 biomacromolecules, namely Chaperone surA and C-peptide.

The molecule most likely forms heterotrimers.
