pdbSelectOcclude

Description

pdbSelectOcclude is an R package for visualizing relationships between protein structural and non-spatial data, and for selecting occluding structures in a 3D molecular visualization environment. The objective of the package is to help improve current selecting (aka brushing) protein structural residues techniques. Currently, most brushing techniques (such as point-and-click) for 3D spatial data do not work well for occluded structures (i.e. molecular structures that are not visible from the surface). The package is targeted for those who are interested in molecular visualization.

This includes the main components: DESCRIPTION, NAMESPACE, man subdirectory and R subdirectory. Additionally, licence, README and subdirectories vignettes, tests, data and inst are also explored. To develop this package, R (version 4.0.2) and Mac platform was used.

Installation

You can install the development version of pdbSelectOcclude like so:

require("devtools")
devtools::install_github("JerrieFeng/pdbSelectOcclude", build_vignettes = TRUE)
library("pdbSelectOcclude")

To run the Shiny App:

#Example of visualizing occluded AA
selAASlider(pdb, "1bm8")

#Example of visualizing occluded protein chains
selChainSlider(pdb2, "1SI4")

Overview

ls("package:pdbSelectOcclude")
data(package = "pdbSelectOcclude") # includes PDB files

pdbSelectOcclude contains 5 functions. The showInfoPDB function takes a PDB file as input, and then returns the AA (amino acid) and chain information of the chosen protein. selAA function allow users to select an [occluded] AA to view and interact with. selAASlider function allow users to interact with any AA with a slider through Shiny App. selChain function allow users to select an [occluded] chain to view and interact with. selChainSlider function allow users to interact with any chain with a slider through Shiny App.

An overview of the package and examples of what it should produce is illustrated below.

Contributions

The author of the package is Jerrie Feng. All the functions rely on bio3d package to read and extract information from the PDB files. selAA and selChain makes use of r3dmol and dplyr to visualize the protein as a 3D molecule. selAASlider and selChainSlider make use of Shiny to create the slider and allow users to interact with the proteins.
