Intraorganellar acidification by V-ATPases: a target in cellproliferation and cancer therapy
(Bentham Science Publishers, 2010)
V-ATPases are multicomponent proton pumps involved in the acidification of singlemembrane intracellular compartments such as endosomes and lysosomes. They couple thehydrolysis of ATP to the translocation of one to two ...

Isolation of Ribosomal Particles from the Unicellular Cyanobacterium Synechocystis sp. PCC 6803
(Bio-Protocol, 2017)
Isolation of ribosomal particles is an essential step in the study of ribosomal components as well as in the analysis of trans-acting factors that interact with the ribosome to regulate protein synthesis and modulate the ...

Regulation of internal promoters in a zinc-responsive operon is influenced by transcription from upstream promoters
(American Society for Microbiology, 2013)
In the cyanobacterium Anabaena sp. strain PCC 7120 (also known as Nostoc sp. strain PCC 7120), a zinc-responsive operon (all4725-all4721) has been described, which contains 4 distinct promoters. The two most upstream ones ...

Depletion of m-type thioredoxin impairs photosynthesis, carbon fixation, and oxidative stress in cyanobacteria
(Oxford University Press, 2021)
Thioredoxins (Trxs) are disulfide oxidoreductases that regulate many biological processes. The m-type thioredoxin (TrxA) is the only Trx present in all oxygenic photosynthetic organisms. Extensive biochemical and proteomic ...

Amino acid transport systems required for diazotrophic growth in the cyanobacterium Anabaena sp. strain PCC 7120
(American Society for Microbiology, 1995)
Uptake of 16 amino acids by the filamentous, heterocyst-forming cyanobacterium Anabaena sp. strain PCC 7120 was characterized with regard to kinetic parameters of transport, intracellular accumulation of the transported ...

Cancer-Stem-Cell Phenotype-Guided Discovery of a Microbiota- Inspired Synthetic Compound Targeting NPM1 for Leukemia
(AMER CHEMICAL SOC, 2023)
The human microbiota plays an important role in human health and disease, through the secretion of metabolites that regulate key biological functions. We propose that microbiota metabolites represent an unexplored chemical ...
