Identification and characterization of small RNAs in the hyperthermophilic archaeon Sulfolobus solfataricus. [PDF]

open access: yesPLoS ONE, 2012
The term RNA silencing (RNA interference, RNAi) describes a set of mechanisms that regulate gene expression in eukaryotes. Small interfering RNAs (siRNA) and microRNAs (miRNAs) are two major types of RNAi-associated small RNAs (smRNAs) found in most ...

Molecular analysis of 3D domain swapping in the acylphosphatase from Escherichia coli

open access: yesActa Crystallographica Section D, Volume 82, Issue 4, Page 336-347, April 2026.
Structures of the monomer and intertwined dimer of the acylphosphatase from E. coli shed light on the molecular basis of its 3D domain swapping.Three‐dimensional domain swapping is a mechanism by which proteins form oligomers. At present, the molecular basis that dictates whether some proteins fold in their monomeric form or as intertwined oligomers is

The return of metabolism: biochemistry and physiology of glycolysis

open access: yesBiological 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 ...

The bindosome is a structural component of the Sulfolobus solfataricus cell envelope [PDF]

open access: yesExtremophiles, 2011
Sugar binding proteins of the thermoacidophile Sulfolobus solfataricus function together with ABC transporters in the uptake of sugars. They are synthesized as precursors with a class III signal peptide that are normally found in archaeal flagellins and bacterial type IV pilins. The functional expression of sugar binding proteins at the cell surface is

Characterization of a hyperthermophilic sulphur-oxidizing biofilm produced by archaea isolated from a hot spring

open access: yesElectronic Journal of Biotechnology, 2017
Background: Sulphur-oxidizing microorganisms are widely used in the biofiltration of total reduced sulphur compounds (odorous and neurotoxic) produced by industries such as the cellulose and petrochemical industries, which include high-temperature ...

Protein Language Model‐Guided Engineering of a 2,3‐Butanediol Dehydrogenase for the Enantioselective Synthesis of Cyclic α‐Hydroxy Ketones

open access: yesAdvanced Science, Volume 13, Issue 18, 27 March 2026.
A (2R,3R)‐butanediol dehydrogenase from Bacillus subtilis (BsBDH) is engineered for the enantioselective synthesis of 2‐hydroxycyclohexanone. A PASS computational design strategy is proposed to enhance the thermostability of BsBDH. Moreover, ESM‐1v combined with ISM is utilized for enhancing and inverting its stereoselectivity.

Transcriptional response to DNA damage in the archaeon Sulfolobus solfataricus [PDF]

open access: yesNucleic Acids Research, 2003
Exposure of cells to DNA-damaging agents triggers a complex biological response involving cell cycle arrest and modulation of gene expression. Genomic sequencing has revealed the presence of archaeal genes homologous to components of the eucaryal nucleotide excision repair (NER) pathway, which is involved in the repair of ultraviolet (UV) light-induced

Control of cyclic oligoadenylate synthesis in a type III CRISPR system

open access: yeseLife, 2018
The CRISPR system for prokaryotic adaptive immunity provides RNA-mediated protection from viruses and mobile genetic elements. When viral RNA transcripts are detected, type III systems adopt an activated state that licenses DNA interference and synthesis

Analysis of nucleotide insertion opposite urea and translesion synthesis across urea by DNA polymerases

open access: yesGenes and Environment, 2022
Urea (Ua) is produced in DNA as the result of oxidative damage to thymine and guanine. It was previously reported that Klenow fragment (Kf) exo− incorporated dATP opposite Ua, and that DNA polymerase β was blocked by Ua.
