| Abstract: |
| It was designed to research the anti-HIV activities of protein MAP30 so as to provide scientific basis and theoretical basis for clinical application, to analyze and predict the protein MAP30 comprehensively using bioinformatics online servers, such as protparam, PHDhtm and PredictProtein. The results were as follows: MAP30 was stable alkali hydrophobin and the sequence thereof comprises three sections of transmembrane spiral structures and a section of disordering bit field; aggregates were formed among the molecules by the disulfide bond on peptide chain, therefore, it was a secretory protein. The protein MAP30 sequence contained signal peptide, a low complexity region and an RIP active region, therefore, it had three functions of cell envelope, isomerase and immune response. The sequence was distributed with N-glycosylation loci, N-myristoylation loci, Shiga/ricin ribosome inactivating protein loci and multi-zone protein kinase phosphorylation loci. |
