Background 8‐Aminoguanosine and 8‐aminoguanine are K+‐sparing natriuretics that increase glucose excretion. Most effects of 8‐aminoguanosine are due to its metabolism to 8‐aminoguanine.

Estimating the size of the solution space of metabolic networks [PDF]
In this work we propose a novel algorithmic strategy that allows for an efficient characterization of the whole set of stable fluxes compatible with the metabolic constraints.

Abstract Ribonuclease E (RNase E) is central to bacterial RNA metabolism. In cyanobacteria, its activity is inhibited by RebA, a key mechanism for controlling cell morphology. Here, we demonstrate that rebA is essential for diazotrophic growth of Anabaena PCC 7120, a filamentous cyanobacterium capable of forming heterocysts—specialized nitrogen‐fixing ...

Elucidating the molecular physiology of lantibiotic NAI-107 production in Microbispora ATCC-PTA-5024 [PDF]
BACKGROUND: The filamentous actinomycete Microbispora ATCC-PTA-5024 produces the lantibiotic NAI-107, which is an antibiotic peptide effective against multidrug-resistant Gram-positive bacteria. In actinomycetes, antibiotic production is often associated

Here, we report that mitochondria from rat skeletal muscle contain a select population of nuclear‐encoded protein‐coding and noncoding RNAs, including 3 microRNAs whose expression tended to be altered by exercise training. These findings suggest that mitochondria‐localized nuclear‐encoded RNAs may play a role in mediating the beneficial adaptive ...

Using in silico models to simulate dual perturbation experiments: procedure development and interpretation of outcomes. [PDF]
BackgroundA growing number of realistic in silico models of metabolic functions are being formulated and can serve as 'dry lab' platforms to prototype and simulate experiments before they are performed.

Phase Separation Regulates Metabolism, Mitochondria, and Diseases
Mitochondrion‐related liquid–liquid phase separation. (1) Phase separation mediates the self‐assembly of mitochondrial nucleoids (mt‐nucleoids). (2) Phase segregation mediates the formation of mitochondrial RNA granules (MRGs). (3) Phase separation mediates the formation of mitochondrial degradosomes.

Defective Processing of Cytoplasmic and Chloroplast Ribosomal RNA in the Absence of Arabidopsis DXO1
ABSTRACT Decapping 5′‐3′ exoribonucleases from the DXO/Rai1 family are highly conserved among eukaryotes and exhibit diverse enzymatic activities depending on the organism. The biochemical and structural properties of the plant DXO1 differ from the yeast and animal counterparts, which is reflected in the in vivo functions of this enzyme.

Bacterial RNA degradation is typically initiated by endoribonucleases and followed by exoribonucleases. Here the authors report the targetome of endoRNase Y in Streptococcus pyogenes, revealing the interplay between RNase Y and 3′-to-5′ exoribonuclease ...

Crystal structure of the S. solfataricus archaeal exosome reveals conformational flexibility in the RNA-binding ring. [PDF]
The exosome complex is an essential RNA 3'-end processing and degradation machinery. In archaeal organisms, the exosome consists of a catalytic ring and an RNA-binding ring, both of which were previously reported to assume three-fold symmetry.Here we ...
