in the process of learning basic biochemistry, as in any other area, much extra class work is required for students before basic concepts, such as those concerning protein structure and properties, are firmly settled. to reach this end we have developed a simple instruction method to teach protein structure in biochemistry courses for medical students. the objectives of this method are to illus...

objectives the overall goal of this study was to carry out a set of comparative analyses of arsr gene in plasmid r773 and bacterial chromosome from escherichia coli bl-21(de3). methods pdb and ncbi databases and chimera, mega4, clc main workbench software and 3d-jigsaw and embl-ebi servers were applied to perform this study. by using these software and servers, multiple analyses including deter...

the automatic assignment of protein secondary structure from three dimensional coordinates is an essentialstep in the characterization of protein structure.although, the recognition of secondary structures suchas alpha-helices and beta-sheets seem straightforward, but there are many different definitions, eachregarding different criteria. we have developed a newalgorithm for protein helix assig...

in the near future, design of a new generation of drugs targeting proteins will be required. considering the complex bond between the drug and protein, the structure and stability of the target protein should be considered. so far, a series of in vitro investigations have been conducted with the aim of predicting drug-biological medium interactions. in these studies, use of spectroscopic method...

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...

background: rotaviruses (rv) are important viral diarrheal agents in calves. vaccination is an optimum measure to prevent bovine rotaviruses (brv) infection. however, little research on brv vp7 vaccine has been done and currently there is no brv vaccine. objective: to prepare a subunit vaccine of brv and investigate its efficacy. methods: total rna was extracted from ma104 cells infected with b...
