NCBI

To search for protein’s sequences

This website provides information about target proteins’ gene sequences and amino acid sequences. We are able to find the protein amino acid sequence we were looking for using this website.

For example: Thioredoxin
We understood through this website that the protein’s amino acid sequence length is 109 amino acids, the sequence is shown in the following picture:

RaptorX

A web Portal for Protein Structure and Function Prediction


It is divided into four parts

  • A.  RaptorX Structure Prediction: template-based tertiary structure prediction
  • B. RaptorX Property Prediction: protein structure property prediction without using templates
  • C. RaptorX Contact Prediction
  • D. RaptorX Binding Prediction

We utilized the part on structure prediction, helping us to express the secondary and tertiary structures.

For example: The fusion protein we designed

A. The first part: Displays amino acid sequence

B. The second part: Visualize the protein

C. The third part tells us information about secondary structure, where the positions of alpha helix or Beta folds are.

Uniprot

Free use of the protein sequence and functions database

Including a large amount of information derived from research papers about protein’s biological function messages. We used this tool to find the active site of our protein.

For example: thioredoxin

Found this protein’s active site through this website

Pymol

Can visualize protein sequences.

Other than the protein’s 3D structure, the amino acid positions can be shown.

For example:fusion protein
We used this software to show the 3D structure, labelling with different colors and showing interfaces, to increase the quality of the picture.

Swiss Model

Protein model database to compare with the given protein

To find the most similar template or the template with highest sequence coverage. By combining different templates, we predict the desired structure of our protein.

For example:fusion protein
We used this software to show the 3D structure, labelling with different colors and showing interfaces, to increase the quality of the picture.

PMV-1.5.7rc1

Add hydrogen bonds to the protein

Since RaptorX does not have the ability to mark hydrogen bonds of the protein structure, this tool can add hydrogen bonds to the protein derived from Raptor X. It can also allow electrons to be attached to the protein, simulating real proteins.

A.Without the hydrogen bonds

B.With the hydrogen bonds

PubChem

Allows downloading of SDF files

Find out the substrate that we are going to combine with the active site, the website allows downloading of SDF files, which can use PyRx to simulate the 3D structure of the substrate connected with the active site.

For example: aflatoxin B1

PyRx

Do docking to combine molecule and ligand

PyRx is a simulating tool built on AutoDock or AutoDock Vina, which can allow us to join our substrates with proteins, simulating the position where they join. PyRx is therefore a strong tool for designing drugs. It also involves the functions and simple clicking interfaces for drug designs, at the same time being a strong visualisation tool.

For example:Fusion protein docking with aflatoxin B1
