Metabolic insights of lactic acid bacteria in reducing off‐flavors and antinutrients in plant‐based fermented dairy alternatives

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 24, Issue 2, March 2025.
Abstract Multiple sensorial, technological, and nutritional challenges must be overcome when developing plant‐based fermented dairy alternatives (PBFDA) to mimic their dairy counterparts. The elimination of plant‐derived off‐flavors (green, earthy, bitter, astringent) and the degradation of antinutrients are crucial quality factors highlighted by the ...

Structural and functional characterization of the aminoacetone utilization microcompartment from Mycobacterium smegmatis MC2 155 [PDF]

open access: yes, 2019
Bacterial microcompartments are proteinacious complexes made by bacteria, which metabolize volatile or cytotoxic chemicals, by sequestering a series of reactions within a selectively permeable shell.

Metagenomic Exploration Uncovers Several Novel ‘Candidatus’ Species Involved in Acetate Metabolism in High‐Ammonia Thermophilic Biogas Processes

open access: yesMicrobial Biotechnology, Volume 18, Issue 3, March 2025.
Metagenomic analysis of three thermophilic species was performed to identify key species for stable biogas production at high free ammonia levels (> 0.7 g/L). Potential acetogens and syntrophic acetate‐oxidising bacteria (SAOB) were recovered by looking for genes of the Wood–Ljungdahl pathway and glycine synthase reductase pathway.

Structure and mechanism of the RNA polymerase II CTD phosphatase Scp1 and large-scale preparation of the RNA polymerase II-TFIIF complex [PDF]

open access: yes, 2006
TFIIF is the only general transcription factor that has been implicated in the preinitiation complex assembly, open complex formation, initiation and transcription elongation. In addition, TFIIF stimulates Fcp1, a central phosphatase needed for recycling

The Mysterious World of Non‐Canonical Caps – What We Know and Why We Need New Sequencing Techniques

open access: yesChemBioChem, Volume 26, Issue 3, February 1, 2025.
This review describes sophisticated methodologies such as LC–MS that enabled the identification of 5’ non‐canonical RNA caps and also surveys so far developed sequencing methods, evaluating their advantages and disadvantages. It emphasizes the need for developing new, reliable sequencing techniques to identify RNA types with non‐canonical caps enabling

HMGA1 drives stem cell, inflammatory pathway, and cell cycle progression genes during lymphoid tumorigenesis [PDF]

open access: yes, 2011
Background Although the high mobility group A1 (HMGA1) gene is widely overexpressed in diverse cancers and portends a poor prognosis in some tumors, the molecular mechanisms that mediate its role in transformation have remained elusive.

Paradigms of convergent evolution in enzymes

open access: yesThe FEBS Journal, Volume 292, Issue 3, Page 537-555, February 2025.
Some enzymes are able to catalyse the same reaction despite possessing different structures. Here, we used a combined strategy of analysing published literature and knowledge‐based computational resources to explore this. We conclude that multiple varieties of convergent functional evolution exist to date, but that it is necessary to investigate ...

Acetate Metabolism: The physiological role of ADP-forming acetyl-CoA synthetase and acetate kinase in Entamoeba histolytica [PDF]

open access: yes, 2017
Entamoeba histolytica is a protozoan parasite that causes amoebic colitis and liver abscess in approximately 90 million people each year, resulting in 50,000-100,000 fatalities.
