Environmental Microbiology, Volume 28, Issue 7, July 2026.A novel polyP‐degrading enzyme with an activity differing from those currently known was found in Haloferax volcanii, conferring the ability for this microbe to grow on extracellular polyP. These findings further our understanding of the potential ecological roles of polyP and how archaea metabolise this essential biopolymer.

The FEBS Journal, Volume 293, Issue 11, Page 3303-3319, June 2026.Characterization of anhydromevalonate phosphate decarboxylase, the UbiD‐family decarboxylase involved in the archaeal mevalonate pathway, was conducted. The enzyme is responsible for the biosynthesis of isoprenoids, such as archaeal membrane lipids, respiratory quinones, and dolichols.

Exploring the Molecular Machinery of Denitrification in Haloferax mediterranei Through Proteomics
Frontiers in Microbiology, 2020 Many proteins and enzymes involved in denitrification in haloarchaea can be inferred to be located between the cytoplasmic membrane and the S-layer, based on the presence of a Tat signal sequence and the orientation of the active site that some of these ...

Life, 2014 In hypersaline environments, haloarchaea (halophilic members of the Archaea) are the dominant organisms, and the viruses that infect them, haloarchaeoviruses are at least ten times more abundant.

The return of metabolism: biochemistry and physiology of glycolysis
Biological Reviews, Volume 101, Issue 2, Page 751-803, April 2026.ABSTRACT Glycolysis is a fundamental metabolic pathway central to the bioenergetics and physiology of virtually all living organisms. In this comprehensive review, we explore the intricate biochemical principles and evolutionary origins of glycolytic pathways, from the classical Embden–Meyerhof–Parnas (EMP) pathway in humans to various prokaryotic and ...

Novel Extended Tetraether Lipids Found in a High‐CO2 Geyser
Environmental Microbiology, Volume 28, Issue 3, March 2026.Characterisation of the archaeal lipidome of the CO2‐rich subsurface aquifer of the Geyser Andernach reveals novel extended tetraether lipids analogous to extended archaeols, likely produced by Candidatus Altiarchaeum, and potentially functioning as a membrane adaptation strategy to nutrient‐deprived conditions.

Frontiers in Microbiology, 2022 Heavy metals are essential micronutrients at low concentrations, serving as cofactors for relevant microbial enzymes (i.e., respiratory nitrate and nitrite reductases NADH dehydrogenase-2, amine oxidase, etc.), but they become harmful cellular ...

The FEBS Journal, Volume 293, Issue 6, Page 1727-1740, March 2026.Two enzymes from the Thermus thermophilus lysine biosynthetic pathway, LysZ and LysY, unexpectedly exhibit substrate promiscuity. They are able to recognize the LysW intermediates utilized by the ArgW‐mediated arginine route, even though the bacterium already possesses the canonical arginine biosynthetic pathway.
