PyRosetta Book

The Gray Lab at Johns Hopkins University has just released PyRosetta, a Python-based interactive platform for accessing the objects and algorithms within the Rosetta protein structure prediction suite.

In addition to the code, the Gray Lab has put together a book that leads the reader through basics of protein structure and energetics to applications in folding, refinement, docking and design. The focus is on enabling users to write custom scripts, so it includes material on Rosetta fundamentals and the appendices have a list of PyRosetta commands and a breakdown of the input files. The book was beta-tested by students during a course at JHU. The course is a series of workshops that teach how to measure and manipulate protein conformations, calculate energies in low- and high-resolution representations, fold proteins from sequence, model variable regions of proteins (loops), dock proteins or small molecules, design protein sequences, and build custom protocols for operations tailored to particular biomolecular applications

The book can be purchased through Lulu:

In a post yesterday on the Bleeding Edge Biotech Blog, Adam Kraut gives an expanded version of his article for Bio-IT World entitled Antibody Docking on the Amazon Cloud describing how Pfizer is leveraging the power and flexibility of cloud computing to run antibody docking simulations using Rosetta. Pfizer with help from the Rosetta Design Group (that’s us) developed an antibody modeling and docking workflow, which they then scaled up and tested on the cloud with help from BioTeam (which Kraut consults for and talks about in his post). This is a fascinating article and certainly the Pfizer/RDG/BioTeam/Rosetta/Amazon synergy is a phenomenon on the bleeding edge.
