چکیده

A chitinase gene from the thermophilic fungus, Thermomyces lanuginosus was amplified from the genomic DNA of the fungus, by PCR technique. The PCR product was cloned into pXcmkn12 vector by TA cloning technique and sequenced. The gene contained five introns and six exons. The deduced protein sequence coded for 390 amino acids and exhibited very high degree of similarity to other endochitinases of mesophilic and thermophilic fungi. The highly conserved catalytic motif, DGLDIDWEYP, suggests that it belongs to family 18 chitinases.

Molecular characterization and expression of a phytase gene from the thermophilic fungus Thermomyces lanuginosus.

The phyA gene encoding an extracellular phytase from the thermophilic fungus Thermomyces lanuginosus was cloned and heterologously expressed, and the recombinant gene product was biochemically characterized. The phyA gene encodes a primary translation product (PhyA) of 475 amino acids (aa) which includes a putative signal peptide (23 aa) and propeptide (10 aa). The deduced amino acid sequence o...

Effect of temperature on respiration of a mesophilic and a thermophilic fungus.

The respiratory rates of mycelia of the mesophilic fungus, Aspergillus niger, and the thermophilic fungus, Thermomyces lanuginosus, were comparable at their respective temperature optima for growth. The respiratory rate of A. niger was independent of changes in temperature between 15 and 40 C. The respiratory rate of T. lanuginosus increased with increase in temperature between 25 and 55 C.

A putative ancestral actin gene present in a thermophilic eukaryote: novel combination of intron positions.

The gene encoding actin in the thermophilic fungus Thermomyces lanuginosus has been isolated and sequenced. It contains five introns, with three being at positions already known to be intron sites in actin genes from other eukaryotes. These three positions have not been found to occur simultaneously in any other organisms to date, suggesting that the actin gene in this fungus may more closely r...

Carbon utilization profile of a thermophilic fungus, Thermomyces lanuginosus using phenotypic microarray

The thermophilic filamentous fungus, Thermomyces lanuginosus produces the largest amount of xylanase reported. In addition to this, it expresses large amount of other enzymes that have been used industrially or have academic interest. Thus, this fungus has a potential to be applied for biomass conversion to produce biofuel or other applications. In this study, the Biolog system was used to char...
