The use of thermostable cellulases is advantageous for the breakdown of lignocellulosic biomass toward the commercial production of biofuels. Previously, we have demonstrated the engineering of an enhanced thermostable family 8 cellulosomal endoglucanase (EC 3.2.1.4), Cel8A, from Clostridium thermocellum, using random error-prone PCR and a combination of(More)
Recent demands for the production of biofuels from lignocellulose led to an increased interest in engineered cellulases from Trichoderma reesei or other fungal sources. While the methods to generate such mutant cellulases on DNA level are straightforward, there is often a bottleneck in their production since a correct posttranslational processing of these(More)
Olive (Olea europaea L.) is an important source of edible oil which was originated in Near-East region. In this study, two cDNA libraries were constructed from young olive leaves and immature olive fruits for generation of ESTs to discover the novel genes and search the function of unknown genes of olive. The randomly selected 3840 colonies were sequenced(More)
Hydrophobins are small proteins, characterised by the presence of eight positionally conserved cysteine residues, and are present in all filamentous asco- and basidiomycetes. They are found on the outer surfaces of cell walls of hyphae and conidia, where they mediate interactions between the fungus and the environment. Hydrophobins are conventionally(More)
A novel gene sequence, with two exons and one intron, encoding a metallothionein (MT) has been identified in durum wheat Triticum durum cv. Balcali85 genomic DNA. Multiple alignment analyses on the cDNA and the translated protein sequences showed that T. durum MT (dMT) can be classified as a type 1 MT. dMT has three Cys-X-Cys motifs in each of the N- and(More)
Current knowledge of resistance (R) genes and their use for genetic improvement in buffalograss (Buchloe dactyloides [Nutt.] Engelm.) lag behind most crop plants. This study was conducted to clone and characterize cDNA encoding R gene-like (RGL) sequences in buffalograss. This report is the first to clone and characterize of buffalograss RGLs. Degenerate(More)
Trichoderma reesei cellulases are important biocatalysts for a wide range of industrial applications that include the paper, feed, and textile industries. T. reesei endoglucanase 1 (egl1) was successfully expressed as an active and stable catalyst in Pichia pastoris for the first time. Codon optimization was applied to egl1 of T. reesei to enhance its(More)
In this study, rational design for Bacillus thermocatenulatus lipase (BTL2) was carried out to lower the activation barrier for hydrolysis of short-chain substrates. In this design, we used computational models for the enzyme-substrate (ES) complexes of tributyrin (C4) and tricaprylin (C8), which were generated through docking and molecular dynamics (MD)(More)
In the last decades, effective cellulose degradation became a major point of interest due to the properties of cellulose as a renewable energy source and the widespread application of cellulases (the cellulose degrading enzymes) in many industrial processes. Effective bioconversion of lignocellulosic biomass into soluble sugars for ethanol production(More)
Trichoderma reesei Rut-C30 is used widely as an expression host for various gene products. We have explored cellular effects caused by the expression of a mutant form of cellobiohydrolase I (CBHI), the major secreted protein of T. reesei using biochemical and transcriptomic analyses and confocal laser scanning microscopy. The mutated CBHI was tagged(More)
