Transcription start site associated RNAs (TSSaRNAs) are ubiquitous in all domains of life.

open access: yesPLoS ONE, 2014
A plethora of non-coding RNAs has been discovered using high-resolution transcriptomics tools, indicating that transcriptional and post-transcriptional regulation is much more complex than previously appreciated.

Regulation of osmoadaptation in the moderate halophile Halobacillus halophilus : chloride, glutamate and switching osmolyte strategies [PDF]

open access: yes, 2008
The moderate halophile Halobacillus halophilus is the paradigm for chloride dependent growth in prokaryotes. Recent experiments shed light on the molecular basis of the chloride dependence that is reviewed here.

A distinct gene expression mechanism for d‐amino acid utilization in hyperthermophilic archaeon Pyrococcus horikoshii

open access: yesThe FEBS Journal, EarlyView.
The genes PH0137, PH0138, and PH0140 form a cluster in the genome of Pyrococcus horikoshii. The PH0140 gene encodes a transcription factor identified as a d‐amino acid‐responsive regulatory protein (DARP). In feast mode, l‐Ile‐bound DARP binds to the promoter and represses transcription of PH0137 and PH0138. In famine mode, DARP binds to d‐allo‐Ile and

Evolutionary rates and gene dispensability associate with replication timing in the Archaeon Sulfolobus islandicus [PDF]

open access: yes, 2010
In bacterial chromosomes, the position of a gene relative to the single origin of replication generally reflects its replication timing, how often it is expressed, and consequently, its rate of evolution.

Structure analysis of biologically important prokaryotic glycopolymers [PDF]

open access: yes, 2013
Of the many post-translational modifications organisms can undertake, glycosylation is the most prevalent and the most diverse. The research in this thesis focuses on the structural characterisation of glycosylation in two classes of glycopolymer (

The double histone fold: Structure, functional implications across the tree of life and relevance to protein design

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract The histone fold is one of the most ancient and versatile structural motifs in protein biology, best known for its role in chromatin organization. A remarkable variation of this motif is the double histone fold (DHF), in which two histone folds are encoded within a single polypeptide chain and assemble intramolecularly into a histone‐like ...

Early evolution of purple retinal pigments on Earth and implications for exoplanet biosignatures

open access: yes, 2018
We propose that retinal-based phototrophy arose early in the evolution of life on Earth, profoundly impacting the development of photosynthesis and creating implications for the search for life beyond our planet.

The effects of added salt on the second virial coefficients of the complete proteome of E. coli [PDF]

open access: yes, 2002
Bacteria typically have a few thousand different proteins. The number of proteins with a given charge is a roughly Gaussian function of charge - centred near zero, and with a width around ten (in units of the charge on the proton).
