The purple membrane of Halobacterium Salinarum carries out a protein, bacteriorhodopsin (bR), which is a model for structure-function studies of membrane proteins. The heterologous expression of integral membrane proteins (IMPS) is difficult. In this study, we reported the heterologous overexpression of bacterio-opsin (bO) in Escherichia coli BL21 (DE3).(More)
Infectious pancreatic necrosis virus (IPNV) is the causal agent of a highly contagious disease that affects many species of fish and shellfish. This virus causes economically significant diseases of farmed rainbow trout, Oncorhynchus mykiss (Walbaum), in Iran, which is often associated with the transmission of pathogens from European resources. In this(More)
Members of the Camelidae (camels, dromedaries, llamas, alpacas, guanacos and vicunas) are known to produce Igs (immunoglobulins) devoid of light chains and CH1s (constant heavy-chain domains). The antigen-specific binding fragments of these heavy-chain antibodies therefore comprise one single domain (the so-called 'VHH') and are of great importance in(More)
Terpenoid synthases constitute a highly diverse gene family producing a wide range of cyclic and acyclic molecules consisting of isoprene (C5) residues. Often a single terpene synthase produces a spectrum of molecules of given chain length, but some terpene synthases can use multiple substrates, producing products of different chain length. Only a few such(More)
Chronic renal allograft dysfunction is the most common cause of graft loss, for which there are multiple risk factors, including obesity before transplantation, which is believed to lower long-term renal allograft survival. One hundred eighty-two kidney transplant recipients were studied. Body mass index (BMI) at the date of transplantation was calculated.(More)
The gus gene is one of the most frequently used reporter genes in transgenic plants. However, this gene can only be used if the selected plant species does not show endogenous GUS activity. Rapeseed (Brassica napus) microspores and microspore-derived embryos (MDEs) were found to exhibit high activity of endogenous β-glucuronidase which interferes with the(More)
Infectious Pancreatic Necrosis Virus (IPNV) is a member of the family Birnaviridae which causes significant losses in the aquaculture industry. To develop a recombinant vaccine for IPNV, a cDNA construct of IPNV VP2-VP3 fusion gene was prepared and cloned into an Escherichia coli (E. coli) expression vector (pET-26b) to obtain recombinant protein products.(More)
In recombinant protein production, quantity and quality are the major challenges particularly for large scale and high-throughput production systems. The present study mainly focuses on computational analysis and in silico systematic discovery of some key functional gene expression elements in microalgae Dunaliella salina as a case study which there is no(More)
Over the past decade there has been a significant growth in bioinformatics databases, tools and resources. Although, bioinformatics is becoming more specific, increasing the number of bioinformatics-wares has made it difficult for researchers to find the most appropriate databases, tools or methods which match their needs. Our coordinated effort has been(More)
The concentrations of heavy metals in Persian Gulf are low, but petrochemical and refinery activities have caused an increase in heavy metal wastes, especially in coastal regions. The present study was done to determine the bioaccumulation of heavy metals in the muscle of white shrimp (Litopenaeus vannamei) using flame atomic absorption spectrophotometry.(More)
