Intracellular trehalase of a hybrid yeast [PDF]

Biochemical Journal, 1965
1. The trehalase found in an extract prepared from a yeast strain that cannot ferment trehalose was studied and characterized. The enzyme is highly specific for trehalose with K(m) 1.02x10(-2)m, and an optimum pH of 6.9. 2. It is inhibited by glucose and by trehalose 6-phosphate, and does not facilitate any significant transglucosylations. 3. pK values

Inhibitory effects of plant latex on trehalase activity and trehalase gene expression in the red flour beetle, Tribolium castaneum (Coleoptera: Tenebrionidae)

European Journal of Entomology, 2014
Plant latex contains proteins and other components that defend plants against herbivorous insects. We determined the inhibitory activity of methanolic extracts of latex obtained from three species of plant: mulberry, Morus alba; jackfruit, Artocarpus ...

Trehalose itself plays a critical role on lipid metabolism: Trehalose increases jejunum cytoplasmic lipid droplets which negatively correlated with mesenteric adipocyte size in both HFD-fed trehalase KO and WT mice

Nutrition & Metabolism, 2020
Background Trehalose is a functional disaccharide that has anti-metabolic activities such as suppression of adipocyte hypertrophy in mice and alleviation of impaired glucose tolerance in humans.

In silico and in vivo analysis reveal a novel gene in Saccharomyces cerevisiae trehalose metabolism

BMC Genomics, 2003
Background The ability to respond rapidly to fluctuations in environmental changes is decisive for cell survival. Under these conditions trehalose has an essential protective function and its concentration increases in response to enhanced expression of ...

Characterization and Functional Analysis of trehalase Related to Chitin Metabolism in Glyphodes pyloalis Walker (Lepidoptera: Pyralidae)

Insects, 2021
Glyphodes pyloalis Walker (G. pyloalis) is a serious pest on mulberry. Due to the increasing pesticide resistance, the development of new and effective environmental methods to control G. pyloalis is needed.

Integrative Study Supports the Role of Trehalose in Carbon Transfer From Fungi to Mycotrophic Orchid

Frontiers in Plant Science, 2021
Orchids rely on mycorrhizal symbiosis, especially in the stage of mycoheterotrophic protocorms, which depend on carbon and energy supply from fungi. The transfer of carbon from fungi to orchids is well-documented, but the identity of compounds ensuring ...

RNAi-mediated abrogation of trehalase expression does not affect trehalase activity in sugarcane [PDF]

SpringerPlus, 2012
AbstractTo engineer trehalose metabolism in sugarcane (Saccharumspp. hybrids) two transgenes were introduced to the genome: trehalose-6-phosphate synthase- phosphatase (TPSP), to increase trehalose biosynthesis and an RNAi transgene specific for trehalase, to abrogate trehalose catabolism.

Trehalase Activity in Arabidopsis thaliana Optimized for 96-well Plates

Bio-Protocol, 2013
Trehalose is a nonreducing disaccharide. It is a common sugar in bacteria, fungi and yeast, where it functions as a carbon source and stress protectant. In contrast, plants, although encoding large trehalose biosynthesis gene families, contain only small

Trehalase Deficiency in a Family

Gastroenterology, 1973
A 24-year-old white man was admitted to University Hospital in Plzen with vomiting and diarrhea, which resulted from the ingestion of mushrooms. He became asymptomatic within 24 hr. Mushroom intolerance was also present in the patient’s father, uncle, and two cousins. Small bowel biopsy, histological examination, and intestinal disaccharidases activity
