Low nitrogen status affects isoflavonoid production and flavonol decoration in Lotus corniculatus
(Elsevier, 2024-03)
Nitrogen availability is key factor for plant metabolism and has a strong impact on the biosynthesis of secondary plant metabolites. A number of these metabolites are involved in the response to stress. In this paper, we ...

Cluster of genes that encode positive and negative elements influencing filament length in a heterocyst-forming cyanobacterium
(American Society for Microbiology, 2013)
The filamentous, heterocyst-forming cyanobacteria perform oxygenic photosynthesis in vegetative cells and nitrogen fixation in heterocysts, and their filaments can be hundreds of cells long. In the model heterocyst-forming ...

DNA polymerase λ, a novel DNA repair enzyme in human cells
(American Society for Biochemistry and Molecular Biology Inc., 2002)
DNA polymerase lambda (pol λ) is a novel family X DNA polymerase that has been suggested to play a role in meiotic recombination and DNA repair. The recent demonstration of an intrinsic 5′-deoxyribose-5-phosphate lyase ...

Haloferax mediterranei Cells as C50 Carotenoid Factories
(MDPI, 2021)
Haloarchaea produce C50 carotenoids such as bacterioruberin, which are of biotechnological in-terest. This study aimed to analyze the effect of different environmental and nutritional conditions on the cellular growth and ...

Sub-cellular localization and complex formation by aminoacyl-tRNA synthetases in cyanobacteria: Evidence for interaction of membrane-anchored ValRS with ATP synthase
(Frontiers Media S.A., 2016)
tRNAs are charged with cognate amino acids by aminoacyl-tRNA synthetases (aaRSs) and subsequently delivered to the ribosome to be used as substrates for gene translation. Whether aminoacyl-tRNAs are channeled to the ribosome ...

Cytochrome c signalosome in mitochondria
(Springer, 2011)
Cytochrome c delicately tilts the balance between cell life (respiration) and cell death (apoptosis). Whereas cell life is governed by transient electron transfer interactions of cytochrome c inside the mitochondria, the ...

Nicotinamide N-methyltransferase (NNMT) regulates the glucocorticoid signaling pathway during the early phase of adipogenesis
(Springer Nature, 2023-05-22)
Obesity is associated with adipose tissue dysfunction through the differentiation and expansion of pre-adipocytes to adipocytes (hyperplasia) and/or increases in size of pre-existing adipocytes (hypertrophy). A cascade of ...

Characterization of the response to zinc deficiency in the cyanobacterium Anabaena sp. strain PCC 7120
(American Society for Microbiology, 2012)
Zur regulators control zinc homeostasis by repressing target genes under zinc-sufficient conditions in a wide variety of bacteria. This paper describes how part of a survey of duplicated genes led to the identification of ...

Ectopic overexpression of the cell wall invertase gene CIN1 leads to dehydration avoidance in tomato
(Oxford University Press, 2015)
Drought stress conditions modify source–sink relations, thereby influencing plant growth, adaptive responses, and consequently crop yield. Invertases are key metabolic enzymes regulating sink activity through the hydrolytic ...

The Efficient Functioning of Photosynthesis and Respiration in Synechocystis sp. PCC 6803 Strictly Requires the Presence of either Cytochrome c6 or Plastocyanin
(Elsevier, 2004)
In cyanobacteria, cytochrome c6 and plastocyanin are able to replace each other as redox carriers in the photosynthetic and respiratory electron transport chains with the synthesis of one or another protein being regulated ...
