proteusPy: A Python Package for Protein Structure and Disulfide Bond Modeling and Analysis

proteusPy is a Python package specializing in the modeling and analysis of proteins of known structure with an initial focus on Disulfide bonds.This package significantly extends the capabilities of the molecular modeling program proteus, (Pabo & Suchanek, 1986), and utilizes a new implementation of the Turtle3D class for disulfide and protein modeling.This initial implementation focuses on the Disulfide class, which implements methods to analyze the protein structure stabilizing element known as a Disulfide Bond, DOI.The work has resulted in a freely-accessible database of over 120,494 disulfide bonds contained within 35,818 proteins in the RCSB Protein Databank.The routines within the library are capable of extracting, comparing, and visualizing the disulfides contained within the database, facilitating analysis and understanding.In addition, the package can readily model disulfide bonds of arbitrary conformation, facilitating predictive analysis.
