PDB Sequence-feature Viewer

NPM version

The sequence-feature view shows a linear representation of the sequence of the protein in a PDB entry and depicts value-added annotation from SIFTS. This including residue-level mapping to UniProt, sequence families (Pfam), structure domains (SCOP, CATH), mutations, binding-site residues, structure quality and secondary structure. By default the sequence-feature view shows the chain that has the maximum number of observed residues.

It is a PDB Component Library component.

PDB Sequence-feature Viewer

Getting Started

It takes only 3 easy steps to get started with PDB Components.

  • Include module files and required dependencies
  • Install the component
  • Use component as custom element anywhere in the page

If you have installed the PDB Component Library in your application then you can directly start using the component as custom element (refer step 3).

1. Include module files and dependencies

Download the module javascript and stylesheet files (pdb.sequence.viewer.min.js and pdb.sequence.viewer.min.css) stored in the 'build' folder. Include the files in your page <head> section.

You'll also need to include the D3.js and AngularJS library file (please refer 'bower.json' file for complete dependency details).

<!-- minified component css -->
<link rel="stylesheet" type="text/css" href="build/pdb.sequence.viewer.min.css">

<!-- Dependencey scripts (these can be skipped if already included in page) -->
<script src="bower_components/d3/d3.min.js"></script>
<script src="bower_components/angular/angular.min.js"></script>

<!-- minified component js -->
<script src="build/pdb.sequence.viewer.min.js"></script>

2. Installation

As soon as you've got the dependencies and library files included in your application page you just need to include following installation script :

I) If you are developing an AngularJs Application

angular.module('myModule', ['pdb.sequence.viewer']);

II) For other Applications

(function () {
  'use strict';
  angular.element(document).ready(function () {
      angular.bootstrap(document, ['pdb.sequence.viewer']);

3. Using component as custom element anywhere in the page

The component can be used as custom element, attribute or class anywhere in the page.

<!-- component as custom element -->
<pdb-seq-viewer entry-id="1aqd" entity-id="1" height="370" width="750"></pdb-seq-viewer>

<!-- component as attribute -->
<div pdb-seq-viewer entry-id="1aqd" entity-id="1" height="370" width="750"></div>

<!-- component as class -->
<div class="pdb-seq-viewer" entry-id="1aqd" entity-id="1" height="370" width="750"></div>



Sr. No. Attribute Values Description
1 entry-id PDB ID
Mandatory attribute!
Example : entry-id="1cbs"
2 entity-id Entity ID
Mandatory attribute!
Example : entity-id="1"
3 height Number
(Optional Attribute)
Example : height="370"
4 width Number

4 subscribe-events Boolean (true/false)
(Optional Attribute)
Default : 'true'
Subscribes to custom events of other PDB Components.
Example : subscribe-events="true"

Custom Events

Use this to subscript/bind events of this component. Event data (available in key = 'eventData') contains information about the residue number, chain, entry and entity, etc.

Sr. No. Event Description
1 PDB.seqViewer.click use this to bind to click event
document.addEventListener('PDB.seqViewer.click', function(e){ //do something on event })
2 PDB.seqViewer.mouseover use this to bind to mouseover event
document.addEventListener('PDB.seqViewer.mouseover', function(e){ //do something on event })
3 PDB.seqViewer.mouseout use this to bind to mouseout event
document.addEventListener('PDB.seqViewer.mouseout', function(e){ //do something on event })
