Although current computational biology software is available and has prompted the development of enzyme–substrate simulation,they are difficult to install and inconvenient to use.This makes the process time-consuming and error-prone.By far there is still a lack of a complete tool which can provide a one-stop service for the enzyme–substrate simulation process.Hence,in this study,several computational biology software was extended development and integrated as a website toolbox named Atomevo.The Atomevo is a free web server providing a user-friendly interface for enzyme–substrate simulation:(1)protein homologous modeling;(2)parallel docking module of Autodock Vina 1.2;(3)automatic modeling builder for Gromacs molecular dynamics simulation package;and(4)Molecular Mechanics/Poisson–Boltzmann Surface Area(MMPBSA)analysis module for receptor–ligand binding affinity analysis.We officially launched the web server and provided instructions through a case for the design and simulation of Candida antarcticalipase B(CalB)fusion protein called Maltose Binding Protein—Thioredoxin A—Candida antarcticalipase B(MBP-TrxA-CalB). 展开更多
