Protein structure determination of insulin of zebra fish (Danio rerio) by homology modeling and structure analysis

The protein sequence of insulin of zebra fish is obtained from UniProt. Due to lack of their structure, structure prediction is necessary, because the structure of protein plays an important role in their function. Our work is based on the production of two protein structure, from the same sequence, by computational approach and finally validates these generated structures. In this work two different widely acceptable online web tool are used for generating structure from the protein sequences of insulin of zebra fish. These are Swiss Model web server and ESyPred3D web server. After getting structure from this two web tool, the structures are passed by a series of quality tests. ProQ web software is used for checking quality of these generated structures. 3d-ss web tool is used for superimposition between two generated structures. It can compare between two structures. The Ramachandran plot is calculated by using VegaZZ software. CASTp (Computer Atlas of Surface Topology of protein) is a web tool, used to predict active sides with their respective volume and area. Finally ProFunc tool is used for analysis of two structures. Key-Words: CASTp, Homology Modeling, ProQ, VegaZZ, Zebra fish insulin
