Sequence and putative regulatory elements in a 5S rRNA gene from a eukaryotic thermophile, Thermomyces lanuginosus

Chitinase from Thermomyces lanuginosus SSBP and its biotechnological applications

Chitinases are ubiquitous class of extracellular enzymes, which have gained attention in the past few years due to their wide biotechnological applications. The effectiveness of conventional insecticides is increasingly compromised by the occurrence of resistance; thus, chitinase offers a potential alternative to the use of chemical fungicides. The thermostable enzymes from thermophilic microorganisms have numerous industrial, medical, environmental and biotechnological applications due to their high stability for temperature and pH. Thermomyces lanuginosus produced a large number of chitinases, of which chitinase I and II are successfully cloned and purified recently. Molecular dynamic simulations revealed that the stability of these enzymes are maintained even at higher temperature. In this review article we have focused on chitinases from different sources, mainly fungal chitinase of T. lanuginosus and its industrial application.

Characteristic electron microscopical projections of the small ribosomal subunit from Thermomyces lanuginosus

Multivariate statistical analysis and hierarchical ascendant classification techniques have been used to sort electron images of small ribosomal subunits from the thermophilic fungus Thermomyces lanuginosus into their characteristic views. Three predominant modes of adsorption to the support were elucidated: right-lateral, left-lateral and asymmetric, showing reproducible detail approaching 1.8 nm resolution. The projections of the fungal complexes appeared almost identical to those of HeLa cells, rat liver and rabbit reticulocytes studied previously in this manner. This result contrasts with the greater variation in fine structural features observed between ribosomal subunits from different prokaryotic species.
