Nucleotides: Structure and Properties [PDF]

, 2005
Nucleotides consist of a nitrogen-containing base, a five-carbon sugar, and one or more phosphate groups. Cells contain many types of nucleotides, which play a central role in a wide variety of cellular processes, including metabolic regulation and the ...

Beyond nocardioform: Transcriptionally active microbes and host responses in equine mucoid placentitis

Equine Veterinary Journal, EarlyView.
Abstract Background Nocardioform placentitis (NP) is an understudied form of equine placentitis historically attributed to nocardioform bacteria, yet it remains uncertain whether these organisms are the sole pathogens involved. Objectives To elucidate the pathophysiology of NP and the host–pathogen interaction. Study Design In vivo clinical multi‐omics

Human FASTK preferentially binds single‐stranded and G‐rich RNA

The FEBS Journal, EarlyView.
Although FASTK is known to play a role in mRNA biology, the mechanism through which it recognizes RNA has yet to be unraveled. Here, we used purified human FASTK to characterize its RNA‐binding properties in vitro. We found that FASTK prefers ssRNA oligonucleotides containing guanines with the potential to form G‐quadruplexes and binds robustly to any ...

Template-directed biopolymerization: tape-copying Turing machines

, 2012
DNA, RNA and proteins are among the most important macromolecules in a living cell. These molecules are polymerized by molecular machines. These natural nano-machines polymerize such macromolecules, adding one monomer at a time, using another linear ...

Enzymatic strategies for phosphorus utilization in periphyton: A study of alkaline phosphatase kinetics in post‐mining lakes

Journal of Phycology, EarlyView.
Abstract Alkaline phosphatase (AP) plays an important role in phosphorus (P) cycling in aquatic ecosystems, particularly under nutrient limitation. In post‐mining lakes of Czechia, periphyton forms extensive mats despite chronic P deficiency, suggesting dissolved organic P (DOP) may serve as a key P source.

The FsrA‐Mediated Iron‐Sparing Response Regulates the Biosynthesis of the Epipeptide EPE in Bacillus subtilis

Molecular Microbiology, EarlyView.
Under iron‐limited conditions, FsrA base‐pairs with the intergenic region between epeX and epeE, enhancing epeE translation and triggering EPE production. Toxin‐mediated cell lysis releases nutrients, including iron, which can be taken up by surviving cells.
