Nitrogen and potassium supplied by phenological stages affect the carotenoid and nutritive content of the tomato fruit

open access: yesNotulae Botanicae Horti Agrobotanici Cluj-Napoca, 2021
The effect of nitrogen (N) and potassium (K) supply by phenological stages of horticultural crops such as tomato has been little explored so far. In this study, we evaluated the impact of N supply in the vegetative stage and K in the reproductive stage ...

Sugars in crop plants

open access: yes, 2011
We review current knowledge of the most abundant sugars, sucrose, maltose, glucose and fructose, in the world's major crop plants. The sucrose-accumulating crops, sugar beet and sugar cane, are included, but the main focus of the review is potato and the

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Novel Cyclic Sugar Imines:  Carbohydrate Mimics and Easily Elaborated Scaffolds for Aza-Sugars

open access: yes, 2016
Representative simple or polyhydroxylated, pyrrolidine (e.g, DRAM) or piperidine (e.g., DNJ) imines not only are potential carbohydrate-processing enzyme inhibitors that may be formed as regioisomeric variants but also are scaffolds that may be rapidly ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Adaptation of the Gut Microbiota to Modern Dietary Sugars and Sweeteners

open access: yesAdvances in Nutrition, 2019
The consumption of sugar has become central to the Western diet. Cost and health concerns associated with sucrose spurred the development and consumption of other sugars and sweeteners, with the average American consuming 10 times more sugar than 100 y ...
