Accumulation and secretion of beta-glucanases have been studied in vivo by using a thermosensitive secretory mutant of Saccharomyces cerevisiae blocked at the endoplasmic reticulum level (sec 18-1). When incubated at the restrictive temperature no accumulation of active glucanases was observed.

Thermus thermophilus is an extremely thermophilic eubacterium that grows optimally at 70-75 degrees C. Because the frequency of DNA damage, such as deamination, depurination and single-strand breaks, increases as the temperature rises, the regulation of expression as well as the

The beta-glycosidase from the hyperthermophilic Archaeon Sulfolobus solfataricus hydrolyzes beta-glycosides following a retaining mechanism based upon the action of two amino acids: Glu387, which acts as the nucleophile of the reaction, and Glu206, which acts as the general acid/base catalyst.

We isolated membrane vesicles from maize (Zea mays L.) coleoptiles and identified in these vesicles a 58 kDa (pm58) and a 60 kDa (pm60) protein by photoaffinity labelling with 5-azido-[7-3H]indole-3-acetic acid ([3H]N3IAA). Photoaffinity labelling was effectively competed for by auxins

The beta-glucosidase from the hyperthermophilic archaeon Pyrococcus furiosus (CelB) is the most thermostable and thermoactive family 1 glycosylhydrolase described to date.
