IMProv - Integrative Modeling Platform
Developed with funding support from
Integrative structural biology requires the aggregation of multiple distinct types of data to generate models that satisfy all inputs. Here, we present IMProv, an app in the Mass Spec Studio that seamlessly combines XL–MS data with other structural data, such as cryo-EM densities and crystallographic structures, for integrative structure modeling using IMP (www.integrativemodeling.org).
Configure an IMP run
The app contains a wizard to upload protein sequences, atomic structures, all available modeling data, and the necessary graphical interfaces for setting the protein topology files and the configuration of IMP. The output is a set of scripts generated from basic templates. These are combined with IMP to initiate a modeling run.
Containers for running IMP
The scripts and data are combined with a container that includes IMP and the environment for running it. The template script for the IMP Python Modeling Interface (PMI v2) supports cryo-EM and XL–MS data, partial X-ray structures or homologies, as well as basic physical restraints, such as sequence connectivity and excluded volume. We have developed deployment bundles for Amazon Web Services, personal computers and we maintain an installation on Compute Canada Resources (Cedar). The associated tutorials describe in detail how to take advantage of these resources.
