Vitamin B6 is a generic term referring to pyridoxine, pyridoxamine, pyridoxal and their
related phosphorylated forms. Pyridoxal 5′-phosphate is the catalytically active form of …

Thiamin is synthesized by most prokaryotes and by eukaryotes such as yeast and plants. In
all cases, the thiazole and pyrimidine moieties are synthesized in separate branches of the …

The human microbiome encodes a large repertoire of biochemical enzymes and pathways,
most of which remain uncharacterized. Here, using a metagenomics-based search strategy …

Here, we characterize a plastidial thioredoxin (TRX) isoform from Arabidopsis thaliana that
defines a previously unknown branch of plastidial TRXs lying between x-and y-type TRXs …

Jumbo phages have attracted much attention by virtue of their extraordinary genome size
and unusual aspects of biology. By performing a comparative genomics analysis of 224 …

Abstract The Calvin-Benson-Bassham (CBB) cycle is responsible for CO2 assimilation and
carbohydrate production in oxyphototrophs. Phosphoribulokinase (PRK) is an essential …

Kinases are a ubiquitous group of enzymes that catalyze the phosphoryl transfer reaction
from a phosphate donor (usually ATP) to a receptor substrate. Although all kinases catalyze …

Quorum sensing is a process of chemical communication that bacteria use to assess cell
population density and synchronize behavior on a community-wide scale. Communication is …

Adenosine kinase (AK) is a key enzyme in the regulation of extracellular adenosine and
intracellular adenylate levels. Inhibitors of adenosine kinase elevate adenosine to levels that …

Sucrose, a glucose–fructose disaccharide, is the main sugar transported in the phloem of
most plants and is the origin of most of the organic matter. Upon arrival in sink tissues, the …
