First crenarchaeal chitinase found in Sulfolobus tokodaii [PDF]

open access: yes, 2012
This is the first description of a functional chitinase gene within the crenarchaeotes. Here we report of the heterologues expression of the ORF BAB65950 from Sulfolobus tokodaii in E. coli.

A Lrp/AsnC Family Transcriptional Regulator Lrp Is Essential for the Pathogenicity of Dickeya oryzae

open access: yesMolecular Plant Pathology, Volume 26, Issue 6, June 2025.
Lrp is crucial for regulating the pathogenicity of Dickeya oryzae by forming a hierarchical regulatory network with other transcriptional regulatory factors and directly modulating the expression of virulence genes. ABSTRACT Dickeya oryzae causes severe soft rot diseases in a range of important crops. To understand its complicated pathogenic mechanisms,

Bio-oxidation of H2S by Sulfolobus metallicus

open access: yesBiotechnology Letters, 2011
Sulfolobus metallicus is a hyperthermophilic and chemolithoautotrophic archaeon that uses elemental sulfur as an energy source. Its ability to oxidize H(2)S was measured either in the presence or absence of elemental sulphur, showing its ability for using both as an energy source. A biotrickling filter was set up and a biofilm of S.

hSSB1 rapidly binds at the sites of DNA double-strand breaks and is required for the efficient recruitment of the MRN complex [PDF]

open access: yes, 2010
hSSB1 is a newly discovered single-stranded DNA (ssDNA)-binding protein that is essential for efficient DNA double-strand break signalling through ATM. However, the mechanism by which hSSB1 functions to allow efficient signalling is unknown.

pH Threshold Impacts Chalcopyrite Bioleaching Dynamics for the Extreme Thermoacidophile Sulfurisphaera ohwakuensis

open access: yesBiotechnology and Bioengineering, Volume 122, Issue 5, Page 1165-1173, May 2025.
Chalcopyrite bioleaching by the extreme thermoacidophile, Sulfurisphaera ohwakuensis. ABSTRACT The extremely thermoacidophilic archaeon Sulfurisphaera ohwakuensis served as the basis for probing how initial pH (pHinitial) affects copper mobilization from chalcopyrite. Screening of small‐scale cultures (75 mL) at 75°C revealed that ~pH 3.0 was a maximal

“Hot standards” for the thermoacidophilic archaeon Sulfolobus solfataricus [PDF]

open access: yesExtremophiles, 2009
Within the archaea, the thermoacidophilic crenarchaeote Sulfolobus solfataricus has become an important model organism for physiology and biochemistry, comparative and functional genomics, as well as, more recently also for systems biology approaches. Within the Sulfolobus Systems Biology ("SulfoSYS")-project the effect of changing growth temperatures ...

A genetic study of SSV1, the prototypical fusellovirus.

open access: yesFrontiers in Microbiology, 2012
Viruses of thermophilic Archaea are unique in both their structures and genomic sequences. The most widespread and arguably best studied are the lemon-shaped fuselloviruses.
