infectious bronchitis virus (ibv) is a contagious pathogen in fowl that results in economic loss in the poultry industry. in this study, the amino acids sequences of three structural proteins m, n, and s1 for five iranian ibv isolated during 1998-2011 have been analyzed. conserved and variable regions, hydrophobic characteristics and identity matrix were determined after alignment by bioedit ve...

Through the exponential development in the specification of sequences and structures of proteins by genome sequencing and structural genomics approaches, there is a growing demand for valid bioinformatics methods to define these proteins function. In this study, our objective is to identify the function of unknown proteins from UCB-1 pistachio rootstock and specify their class...

Yaba virus proteins were characterized by polyacrylamide gel electrophoresis. Electrophoresis of Yaba virion (proteins) dissociated by sodium dodecyl sulfate and 2-mercaptoethanol in continuous and discontinuous buffer systems yielded 37 polypeptide species by staining and by counting bands of radioactively labeled polypeptides. The molecular weights of the viral polypeptide species were found...

Expression of eukaryotic proteins in E. coli often results in their aggregation. Proper folding and solubility of therapeutical proteins are the pre-requisite for their bioactivity. This is not achieved in cytoplasmic expression in E. coli because of the absence of disulfide bonds formation. A novel expression/secretion vector was constructed which exploited β-lactamase signal sequence to trans...

proteins are fundamental components of cells which mediate many essential biological processes. proteomics is a rapidly growing field for the study of proteome, the protein complement expressed by the genome of an organism or cell type. the large-scale analysis of proteins leads to a more comprehensive view of molecular and cellular pathways that improves the overall understanding of the comple...

Introduction: Hepatitis C virus (HCV) infection is a major public health problem which influences about 170 million people worldwide. Different types of vaccines have been designed using HCV structural proteins to control the viral infection. The core nucleocapsid protein is one of the most conserved proteins and a desirable target for HCV vaccines, especially the protein-based vaccines. In cur...

the genome of iranian wheat stripe virus (iwsv), a tentative member of the genus tenuivirus, is comprised of three ambisense and one negative sense rna segments. the coat and non-structural proteins encoded by the vcrna3 and vrna4 genes, respectively, were efficiently translated in vitro. translated proteins of vcrna3 and vrna4 transcripts were approximately 35000 and 22000 in mr, respectively,...

HeLa cells infected with Sindbis virus were found to contain five species of nonvirion proteins besides the structural proteins of the virus. Some of the nonvirion proteins were found to serve as precursors to the viral structural proteins in a pulse-chase experiment.

introduction: proteins are food ingredients with critical functional properties and participation in developing food products. so far, functional properties of several plant proteins such as pea, chickpea and lentil, groundnut, beach pea and bayberry have been investigated. nowadays, there is an increasing demand for plant proteins because they are available and inexpensive. legume proteins are...
