On the ancestral UDP-glucose pyrophosphorylase activity of GalF from Escherichia coli
(Frontiers Research Foundation, 2015-11)
In bacteria, UDP-glucose is a central intermediate in carbohydrate metabolism. The enzyme responsible for its synthesis is encoded by the galU gene and its deletion generates cells unable to ferment galactose. In some ...
Changes in carbohydrate content and enzymes related activity during Cyphomandra betacea Sendt. fruit maturation.
(Elsevier Science, 2005-12)
Changes in sugar content and activities of invertase (EC 3.2.1.26) and sucrose synthase (EC 2.4.1.13) were measured throughout fruit development in tree tomato (Cyphomandra betacea (Cav) Sendtn.). Fruit of C. betacea ...
The ectomycorrhizal basidiomycete Laccaria bicolor releases a secreted β-1,4 endoglucanase that plays a key role in symbiosis development
(Wiley Blackwell Publishing, Inc, 2018-12)
In ectomycorrhiza, root ingress and colonization of the apoplast by colonizing hyphae is thought to rely mainly on the mechanical force that results from hyphal tip growth, but this could be enhanced by secretion of ...
Pre-Eclampsia Placental Carbohydrate Metabolism Regulating Enzymes ActivityActividad de Enzimas Reguladoras del Metabolismo de Carbohidratos en la Placenta Preeclámptica
(Universidad Nacional Mayor de San Marcos, Facultad de Medicina Humana, 1996)
Aminopeptidase activity is related to the amino acids composition of the food in passerine birds
(PeerJ, 2017-12)
Background. Passerine birds exploit different kinds of feeding habits and they have to face seasonal changes in food availability. Therefore, the composition of the principal nutrient in their food differs from the usual. ...
Proteomic analysis of secretomes from Bacillus sp. AR03: characterization of enzymatic cocktails active on complex carbohydrates for xylooligosaccharides production
(Taylor & Francis, 2021-01)
Bacillus sp. AR03 have been described as an important producer of carbohydrate-active enzymes (CAZymes) when growing in a peptone-based medium supplemented with simple sugars and/or carboxymethyl cellulose (CMC) as carbon ...
Modulation of digestive enzyme activities in the avian digestive tract in relation to diet composition and quality
(Springer Heidelberg, 2017-02)
In nature, birds are faced with variable food sources that may differ in composition (protein vs. carbohydrates) and quality (highly digestible material vs. indigestible fiber). Studies in passerine birds and some commercial ...
Intestinal digestive enzyme modulation in house sparrow nestlings occurs within 24 h of a change in diet composition
(Company of Biologists, 2017-08)
Nestling house sparrows near fledging age (12 days) were previously found to reversibly modulate the activity of their intestinal digestive enzymes in response to changes in diet composition. However, it is not known how ...
Intramolecular azide-alkene cycloaddition-elimination reaction in an aldohex-2-enonic acid derivative
(Elsevier, 2019-09)
A 6-azido-2-tosylenolate, obtained from D-glucono-1,5-lactone in six steps, underwent an intramolecular cycloaddition–elimination pathway under mild conditions, yielding a chiral, substituted 5,6-dihydro-4H-pyrrolo ...
Liver carbohydrates metabolism: A new islet-neogenesis associated protein peptide (INGAP-PP) target
(Elsevier Science Inc, 2018-03)
Islet-Neogenesis Associated Protein-Pentadecapeptide (INGAP-PP) increases β-cell mass and enhances glucose and amino acids-induced insulin secretion. Our aim was to demonstrate its effect on liver metabolism. For that ...
