Evidence for a modulation of neutral trehalase activity by Ca2+ and cAMP signaling pathways in Saccharomyces cerevisiae

Brazilian Journal of Medical and Biological Research, 2002
Saccharomyces cerevisiae neutral trehalase (encoded by NTH1) is regulated by cAMP-dependent protein kinase (PKA) and by an endogenous modulator protein.

Trealose e trealase em tenebrio molitor L Trehalose and Trehalase in Tenebrio molitor L

Memorias do Instituto Oswaldo Cruz, 1972
Foi estudada a concentração em trealose e a atividade em trealase do Tenebrio molitor L. durante as tres fases da metamorfose (larva, ninfa, imago). Verificou-se que na larva e no adulto os valores são mais elevados conforme a curva da fig. 3. A trealose

Risks for human health related to the presence of plant lectins in food

EFSA Journal, Volume 24, Issue 1, January 2026.
Abstract The European Commission asked the European Food Safety Authority (EFSA) to assess the risk related to the presence of plant lectins in food. Based on the available evidence, the CONTAM Panel considered only phytohaemagglutinin (PHA), a legume lectin from beans (Phaseolus sp.), for the risk characterisation.

Combined lactase and trehalase deficiency as a cause of blood lose in young man

Czech Journal of Food Sciences
Trehalose is a disaccharide composed of two glucose that can be found in various plant and animal species. Mammals are not able to synthesize trehalose but it is usually easily enzymatically broken down into 2 molecules of glucose.

Long-term effects of the trehalase inhibitor trehazolin on trehalase activity in locust flight muscle [PDF]

Journal of Experimental Biology, 2010
SUMMARY Trehalase (EC 3.2.1.28) hydrolyzes the main haemolymph sugar of insects, trehalose, into the essential cellular substrate glucose. Trehalase in locust flight muscle is bound to membranes that appear in the microsomal fraction upon tissue fractionation, but the exact location in vivo has remained elusive.

Trehalose 6‐phosphate – a central regulator at the crossroads of sugar signalling, metabolism, and development

New Phytologist, Volume 248, Issue 5, Page 2243-2250, December 2025.
Summary In mammals, blood sugar levels are tightly controlled by two hormones: insulin and glucagon. In flowering plants, a comparable regulatory mechanism exists, mediated by the sugar‐signalling molecule trehalose 6‐phosphate (Tre6P). Similar to insulin, Tre6P functions as a signal and negative feedback regulator of sucrose, the main transport sugar ...

Hydrogen‐Deuterium Exchange Mass Spectrometry for Molecular Glue Characterization

Advanced Science, Volume 12, Issue 41, November 6, 2025.
Molecular glues that stabilize protein–protein interactions are challenging to identify. Here, hydrogen‐deuterium exchange mass spectrometry can show and reveal gluing mechanisms that vary between protein binding partners. Abstract Molecular glues are powerful bioactive molecules that stabilize protein–protein interactions.

The activity of saccharolytic enzymes in Collembola is associated with species affinity for caves

International Journal of Speleology, 2018
The activity of enzymes associated with digestion can reflect food availability and feeding preferences of invertebrates in a particular habitat. Caves are mostly nutrient-poor habitats lacking primary production.
