An Ecological Basis for Dual Genetic Code Expansion in Marine Deltaproteobacteria
Frontiers in Microbiology, 2021 Marine benthic environments may be shaped by anthropogenic and other localized events, leading to changes in microbial community composition evident decades after a disturbance.

Role of selenium in the pathophysiology of cardiorenal anaemia syndrome
ESC Heart Failure, Volume 12, Issue 2, Page 770-780, April 2025.Abstract Chronic kidney disease (CKD) and cardiovascular disease (CVD) have multiple bidirectional mechanisms, and anaemia is one of the critical factors that are associated with the progression of the two disorders [referred to as cardiorenal anaemia syndrome (CRAS)].

Naturally Occurring tRNAs With Non-canonical Structures
Frontiers in Microbiology, 2020 Transfer RNA (tRNA) is the central molecule in genetically encoded protein synthesis. Most tRNA species were found to be very similar in structure: the well-known cloverleaf secondary structure and L-shaped tertiary structure.

Unconventional genetic code systems in archaea
Frontiers in Microbiology, 2022 Archaea constitute the third domain of life, distinct from bacteria and eukaryotes given their ability to tolerate extreme environments. To survive these harsh conditions, certain archaeal lineages possess unique genetic code systems to encode either ...

Microbial distribution of selenocysteine lyase [PDF]
Journal of Bacteriology, 1983 We studied the distribution of selenocysteine lyase, a novel enzyme catalyzing the conversion of selenocysteine into alanine and H2Se, which we first demonstrated in various mammalian tissues (Esaki et al., J. Biol. Chem. 257:4386-4391, 1982). Enzyme activity was found in various bacteria such as Alcaligenes viscolactis and Pseudomonas alkanolytica. No

The relationship between cellular protein content and selenium accumulation in freshwater microalgae
Integrated Environmental Assessment and Management, EarlyView.Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...

Selenocysteine: the 21st amino acid [PDF]
Molecular Microbiology, 1991 SummaryGreat excitement was elicited in the field of selenium biochemistry in 1986 by the parallel discoveries that the genes encoding the selenoproteins glutathione peroxidase and bacterial formate dehydrogenase each contain an in‐frame TGA codon within their coding sequence.

Journal of Applied Toxicology, EarlyView.ABSTRACT Selenium (Se) is an essential micronutrient that participates in redox regulation and cellular homeostasis. Selenium‐containing ionic liquids (ILsSe) have emerged as hybrid compounds combining the properties of organoselenium molecules with the tunable features of ionic liquids.
