Inductively Coupled Plasma Mass Spectrometry Performance for the Measurement of Key Serum Minerals: A Comparative Study With Standard Quantification Methods

open access: yesJournal of Clinical Laboratory Analysis, Volume 39, Issue 2, January 2025.
Analysis of real‐world cross‐sectional study data revealed relative errors between the standard method and ICP‐MS for the different minerals tested. Additionally, several outliers were observed exclusively in the ICP‐MS results, likely due to hemolysis or other unidentified factors.

Novel resources to investigate leaf plasmodesmata formation in C3 and C4 monocots

open access: yesThe Plant Journal, Volume 120, Issue 5, Page 2207-2225, December 2024.
SUMMARY Plasmodesmata (PD) are nanochannels that facilitate cell‐to‐cell transport in plants. More productive and photosynthetically efficient C4 plants form more PD at the mesophyll (M)‐bundle sheath (BS) interface in their leaves than their less efficient C3 relatives.

A functional RNase P protein subunit of bacterial origin in some eukaryotes [PDF]

open access: yes, 2011
RNase P catalyzes 5′-maturation of tRNAs. While bacterial RNase P comprises an RNA catalyst and a protein cofactor, the eukaryotic (nuclear) variant contains an RNA and up to ten proteins, all unrelated to the bacterial protein.

Defects in Polynucleotide phosphorylase impairs virulence in Escherichia coli O157:H7

open access: yesFrontiers in Microbiology, 2015
Polynucleotide phosphorylase (PNPase) is reported to regulate virulence in Salmonella, Yersinia spp. and Campylobacter jejuni, yet its role in Escherichia coli O157:H7 has not been investigated. To gain insights into its roles in E.

Electron Transfer Precedes ATP Hydrolysis during Nitrogenase Catalysis [PDF]

open access: yes, 2013
The biological reduction of N2 to NH3 catalyzed by Mo-dependent nitrogenase requires at least eight rounds of a complex cycle of events associated with ATP-driven electron transfer (ET) from the Fe protein to the catalytic MoFe protein, with each ET ...

Transgenesis of mammalian PABP reveals mRNA polyadenylation as a general stress response mechanism in bacteria

open access: yesiScience, 2021
Summary: In eukaryotes, mRNA 3′-polyadenylation triggers poly(A) binding protein (PABP) recruitment and stabilization. In a stark contrast, polyadenylation marks mRNAs for degradation in bacteria.

Strategies for Detecting Aminoacylation and Aminoacyl‐tRNA Editing in vitro and in Cells

open access: yesIsrael Journal of Chemistry, Volume 64, Issue 8-9, September 2024.
Abstract Aminoacyl‐tRNA synthetases (aaRSs) maintain translational fidelity by ensuring the formation of correct aminoacyl‐tRNA pairs. Numerous point mutations in human aaRSs have been linked to disease phenotypes. Structural studies of aaRSs from human pathogens encoding unique domains support these enzymes as potential candidates for therapeutics ...

Calcium binding to a remote site can replace magnesium as cofactor for mitochondrial Hsp90 (TRAP1) ATPase activity. [PDF]

open access: yes, 2018
The Hsp90 molecular chaperones are ATP-dependent enzymes that maintain protein homeostasis and regulate many essential cellular processes. Higher eukaryotes have organelle-specific Hsp90 paralogs that are adapted to each subcellular environment.
