2025年1月13日 · Sucrase is an enzyme in carbohydrate metabolism, catalyzing the hydrolysis of sucrose into glucose and fructose. This process is essential for energy production and various metabolic pathways. Understanding sucrase dynamics offers insights into digestive health and potential therapeutic targets for disorders related to carbohydrate digestion.

Sucrose-controlled upstream open reading frame (SC-uORF) exists at the 5′ leader region of Scbzip44 's main ORF, which inhibits sucrose accumulation through post-transcriptional regulatory mechanisms. Sucrose transporters (SWEET1a/4a/4b/13c, TST, SUT1, SUT4 and SUT5) are crucial for sucrose translocation from source to sink.

2024年3月15日 · This review reflects progress and prospects in the regulatory mechanism for maximum sucrose accumulation, including the role of sucrose metabolizing enzymes, sugar transporters and the elucidation of post-transcriptional control of sucrose-induced regulation of translation (SIRT) in the accumulation of sucrose.

2004年6月1日 · The sucrose-cleaving enzymes are pivotal to maintaining the balance between both sugar signals and metabolic paths. Different sensing mechanisms are activated by hexoses and by other downstream metabolites, and also by sucrose itself.

Lactic acid bacteria (LAB) employ sucrase-type enzymes to convert sucrose into homopolysaccharides consisting of either glucosyl units (glucans) or fructosyl units (fructans). The enzymes involved are labeled glucansucrases (GS) and fructansucrases (FS), respectively.

1999年5月4日 · SacC is an extracellular sucrase that can catalyse sucrose hydrolysation into fructose and glucose. You might find these chapters and articles relevant to this topic. Habibullah Nadeem, ... Muhammad Riaz, in Process Biochemistry, 2015.

Sucrose cleavage is vital to multicellular plants, not only for the allocation of crucial carbon resources but also for the initiation of hexose-based sugar signals in importing structures. Only the invertase and reversible sucrose synthase reactions catalyze known paths of sucrose breakdown in vivo.

Sucrase is secreted by the tips of the villi of the epithelium in the small intestine. Its levels are reduced in response to villi-blunting events such as celiac sprue and the inflammation associated with the disorder. The levels increase in pregnancy, …

Sucrose metabolism plays pivotal roles in development, stress response, and yield formation, mainly by generating a range of sugars as metabolites to fuel growth and synthesize essential compounds (including protein, cellulose, and starch) and as signals to regulate expression of microRNAs, transcription factors, and other genes and for crosstal...

Sucrase, any member of a group of enzymes present in yeast and in the intestinal mucosa of animals that catalyze the hydrolysis of cane sugar, or sucrose, to the simple sugars glucose and fructose. Granules of sucrase localize in the brush border …
