[ 1 ] - Resistance mechanism of human immunodeficiency virus type-1 protease to inhibitors: A molecular dynamic approach

Human immunodeficiency virus type 1 (HIV-1) protease inhibitors comprise an important class of drugs used in HIV treatments. However, mutations of protease genes accelerated by low fidelity of reverse transcriptase yield drug resistant mutants of reduced affinities for the inhibitors. This problem is considered to be a serious barrier against HIV treatment for the foreseeable future. In this st...

[ 2 ] - A tri state mechanism for oxygen release in fish hemoglobin: Using Barbus sharpeyi as a model

Hemoglobin is a porphyrin containing protein with an a2b2 tetrameric structure and like other porphyrin compounds shows spectral behavior of species specific characteristics. Researchers tend to relate bands in the hemoglobin spectra to certain structural and/or functional features. Given the fact that hemoglobin is the main oxygen carrier in animals functioning through the Oxy«Deoxy equilibriu...

[ 3 ] - Mechanistic prospective for human PrPC conversion to PrPSc: Molecular dynamic insights

PrPC conversion to PrPSc isoform is the main known cause for prion diseases including Crutzfeldt-Jakob, Gerstmann-Sträussler-Sheinker syndrome and fatal familial insomnia in human. The precise mechanism underling this conversion is yet to be well understood. In the present work,  using the coordinate file of PrPC (available on the Protein Data Bank) as a starting structure, separate molecular d...

[ 4 ] - The effect of pH on recombinant C-terminal domain of Botulinum Neurotoxin type E (rBoNT/E-HCC)

Recombinant proteins are tending to be the most favorable vaccine-candidates against botulism. Recombinant Carboxy-terminal of botulinum neurotoxin serotype E (rBoNT/E-HCC) has been introduced as an efficient vaccine against botulism type E. In this report, we made an effort to investigate the effect of different pH on protein structure to assess if rBoNT/E-HCC could be used as a vaccine for or...
