background: fasciola species are parasitic trematode with world wide distribution that infects wild and domesticated herbivores, particularly ruminants. the aim of the present study was to investigate the intra species variations of f. gigantica, from goats and buffalos isolates in two common geographic climates of iran. methods: fasciola species were collected from goat, buffalo, sheep, and ca...

The nucleotide and deduced amino acid sequences of the phosphoprotein (P) mRNA of bovine respiratory syncytial virus (BRSV) strain A51908 have been determined. The P mRNA is 860 nucleotides long with a single large open reading frame and the encoded polypeptide is 241 amino acids long. Comparison with the corresponding sequences of human respiratory syncytial virus (HRSV) subgroups A and B reve...

an experiment was conducted to reevaluate the digestible lysine requirement of arian male broilers by comparing the performance of chicks fed different levels of cottonseed meal (csm) on a total amino acid (aa) versus a digestible aa basis. four hundred and thirty two (432) arian male broiler chicks were allotted to 18 treatments with four repli-cates of six chicks each in a completely randomiz...

Supplementary Figure 1. Proteorhodopsin amino acid sequence alignment. Multiple alignment of the predicted aminoacid sequences of PR in Dokdonia sp. MED134 and Polaribacter sp. MED152 compared to tentative Bacteroidetes orthologs and SAR86 and P. ubique sequences. Predicted transmembrane regions are marked by boxes with solid lines. Gray shading indicates conserved amino acid positions. Key ami...

Background: Trichophyton tonsurans is one of the dermatophyte fungi which invades the skin and hair of human. Several properties of this fungus have been investigated so far. However a few studies were carried out in the field of molecular biology of this fungus. In the present study, we tried to identify the Squalene epoxidase gene which is related to synthesis of ergosterol in this fungus. Me...

The genomic and cDNA clones encoding cellobiohydrolase II (CBHII) have been isolated and sequenced from a native Iranian isolate of Trichoderma parceramosum, a high cellulolytic enzymes producer isolate. This represents the first report of cbhII gene from this organism. Comparison of genomic and cDNA sequences indicates this gene contains three short introns and also an open reading frame codin...

All genome sequence data contains inherent information in it. Shannon's uncertainty theory can be used to measure how much information a sequence has. Here we show that the amount of information in sequences from metagenomes correlates with the number of similar sequences that will be found by comparison to databases of known sequences. Hence, a sequence with more information (higher uncertaint...

Background: Pomegranate fruit (Punica granatum L.) is a rich source of anthocyanin pigments resulting in vibrant colours and anti-oxidant contents. Although the intensity and pattern of anthocyanin biosynthesis in fruit are strongly influenced by R2R3-MYB transcription factors, little is known about the regulation and role of MYB in anthocyanin pathway of pomegranate. Objectives: The present st...

objective(s): production of a recombinant and immunogenic antigen using dengue virus type-3 envelope protein is a key point in dengue vaccine development and diagnostic researches. the goals of this study were providing a recombinant protein from dengue virus type-3 envelope protein and evaluation of its immunogenicity in mice. materials and methods: multiple amino acid sequences of different i...

The amino acid sequences of proteins determine their three-dimensional structures and functions. However, how sequence information is related to structures and functions is still enigmatic. In this study, we show that at least a part of the sequence information can be extracted by treating amino acid sequences of proteins as a collection of English words, based on a working hypothesis that amin...
