Abstract:The aim of this study was to analyze the primary and spatial structure of DfrA12 protein and provide theoretical basis for study on the in-depth research of structure and function. Bioinformatics analysis softwares such as Expasy, TMHMM 2.0, SignalP 4.0, SOPMA and GENO3D were used to analyse and predict the primary and senior structure of DfrA12 protein. The results showed that DfrA12 protein was composed by 165 amino acids, rich in Alpha Helix and Random coil structure. This protein had no signal peptide and transmembrane region, located in intracellular membrane. The three-dimensional structure of the protein was constructed by homology modeling. This study will lay a foundation for further research on structure and biological function of DfrA12 protein.
