Biology

A Protocol for Computer-Based Protein Structure and Function Prediction

Ambrish Roy^1,2, Dong Xu¹, Jonathan Poisson¹, Yang Zhang^1,2

¹Center for Computational Medicine and Bioinformatics, University of Michigan , ²Center for Bioinformatics and Department of Molecular Bioscience, University of Kansas

Guidelines for computer based structural and functional characterization of protein using the I-TASSER pipeline is described. Starting from query protein sequence, 3D models are generated using multiple threading alignments and iterative structural assembly simulations. Functional inferences are thereafter drawn based on matches to proteins with known structure and functions.

¹Department of Medicine, Zhejiang Academy of Traditional Chinese Medicine, ²Department of Orthopaedic Surgery, Tongde Hospital of Zhejiang Province, ³Institute of Orthopaedics and Traumatology, First Affiliated Hospital of Zhejiang Chinese Medical University, ⁴Department of Clinical Laboratory, Tongde Hospital of Zhejiang Province

This study presents an improved rabbit model infected with Staphylococcus aureus by blocking the same amount of bacteria in bone marrow. Vancomycin loaded calcium sulphate and autogenous bone are used for antibiotic and bone repair treatment. The protocol could be helpful for studying bone infection and regeneration.

Engineering
