Structural Analysis of Disulfide Bonds in the RCSB Protein Data Bank Using proteusPy.

A structural analysis of disulfide bonds extracted from the RCSB Protein Data Bank (PDB) is presented. This analysis utilized the proteusPy Python package and provides a statistical basis for yielding a dataset of geometrically reasonable disulfide bond structures. Additionally, a method for quantization of dihedral angles to reduce structural complexity and create disulfide structural classes is described. This method allows for the segmentation of the disulfide bonds into structural families. The results of this analysis provide a framework for understanding the geometric and structural families of disulfide bonds in the RCSB databank.
