The FEBS Journal, EarlyView.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.

The FEBS Journal, EarlyView.Small protein MtrR is a regulator of the Mtr methyltransferase complex in Methanosarcina mazei. It binds specifically to the MtrA subunit and modulates Mtr activity in response to hydrogen (H2) availability. Deleting mtrR impairs growth in the presence but not absence of H2, indicating its role in directing methyl transfer toward an energy‐conserving ...

Bacterial Genes Outnumber Archaeal Genes in Eukaryotic Genomes
bioRxiv, 2019 The origin of eukaryotes is one of evolution’s most important transitions, yet it is still poorly understood. Evidence for how it occurred should be preserved in eukaryotic genomes.

Polyesterase activity and thermostability of carboxylesterases from Thermoleophilum album YS‐3
The FEBS Journal, EarlyView.Three novel α/β‐hydrolases from thermophilic bacterium Thermoleophilum album display carboxylesterase and polyesterase activity. These enzymes hydrolyse PET, PLA and PCL both at high and moderate temperatures. TA21 shows superior activity, efficiently converting MHET to terephthalic acid. Structural features underlying substrate binding highlight their

In silico identification of archaeal DNA-binding proteins
BioinformaticsAbstract Motivation The rapid advancement of next-generation sequencing technologies has generated an immense volume of genetic data. However, these data are unevenly distributed, with well-studied organisms being disproportionately represented, while other organisms, such as from archaea ...

Characterization of TPP-binding proteins in Methanococci archaeal species [PDF]
Bioinformation, 2016 Acetolactate synthase (ALS) is a highly conserved protein family responsible for producing branched chain amino acids. In Methanocaldococcus jannaschii, two ALS proteins, MJ0277 and MJ0663 exist though variations in features between them are noted. Researchers are quick to examine MJ0277 homologs due to their increased function and close relationship ...

S‐Adenosylmethionine (SAM) hydrolases counter increased SAM epimerisation in thermophilic archaea
The FEBS Journal, EarlyView.S‐Adenosyl‐l‐methionine (SAM) is a vital enzyme cofactor. Epimerisation at the sulfonium centre of biologically active (SS,SCα)‐SAM is driven by heat, yielding biologically inactive (RS,SCα)‐SAM. Here, two novel archaeal SAM hydrolases from the thermophilic Sulfolobus acidocaldarius and the halophilic Haloferax volcanii are shown to cleave (RS,SCα)‐SAM.
