stru.part: Partition of Structural Regions

In ptm: Analyses of Protein Post-Translational Modifications

Partition of Structural Regions

Description

Carries out a partition of the structural regions of a given protein.

Usage

stru.part(pdb, cutoff = 0.25)

Arguments

pdb	is either a PDB id, or the path to a pdb file
cutoff	accessibility below which a residue is considered to be buried.

Details

The accessibilities of a residue computed in the complex (ACCc) and in the monomer (ACCm) allow to distinguish four structural regions as follows.

Interior: ACCc < cutoff & (ACCm - ACCc) = 0.

Surface: ACCc > cutoff & (ACCm - ACCc) = 0.

Support: ACCm < cutoff & (ACCm - ACCc) > 0.

Rim: ACCc > cutoff & (ACCm - ACCc) > 0.

Core: ACCm > cutoff & ACCc < cutoff.

Value

A dataframe where each residue is assigned to one of the four structural groups considered.
