ABSTRACT
The aim of In-silico structural analysis and Protein disorder prediction
for HPV type 16 E7 virus proteins is to solve the problem of designing
vaccine against cervical cancer. The simultaneous structural analysis of
E7 proteins out of 50 different HPV strains was carried out for
prediction and validation, by using different bioinformatics tools such as
CPH Model,TMHMM Server,DisEMBL and GlobPlot. In this CPH
Model gives the template recognition, which is based on profile-profile
alignment and it also create a model for HPV type 16 E7 protein
sequence. The TMHMM Server gives prediction of transmembrane
helices and discriminate between soluble and membrane proteins with
high degree of accuracy show as graphical form. DisEMBL gives
prediction of disordered/unstructured regions within a protein sequence
of HPV 16 E7 protein andGlobPlot also predict theorder/globularity and
disordered domain for protein sequence.
