Identification, characterization and classification of prokaryotic nucleoid‐associated proteins

open access: yesMolecular Microbiology, Volume 123, Issue 3, Page 206-217, March 2025.
Nucleoid‐associated proteins (NAPs) structure DNA by either bending, wrapping, bridging, or forming protein filaments on the DNA. We review newly identified NAPs and provide a list of simple biochemical assays to study the DNA‐structuring properties of novel NAPs. Abstract Common throughout life is the need to compact and organize the genome.

Chromatin and gene regulation in archaea

open access: yesMolecular Microbiology, Volume 123, Issue 3, Page 218-231, March 2025.
Recent data from diverse archaea with different repertoires of nucleoid‐associated proteins show a common genome‐wide chromatin organisation where chromatin maintains access to gene promoters independently of transcription activity. Abstract The chromatinisation of DNA by nucleoid‐associated proteins (NAPs) in archaea ‘formats’ the genome structure in ...

Amidst multiple binding orientations on fork DNA, Saccharolobus MCM helicase proceeds N-first for unwinding

open access: yeseLife, 2019
DNA replication requires that the duplex genomic DNA strands be separated; a function that is implemented by ring-shaped hexameric helicases in all Domains.

Differential active site loop conformations mediate promiscuous activities in the lactonase SsoPox.

open access: yesPLoS ONE, 2013
Enzymes are proficient catalysts that enable fast rates of Michaelis-complex formation, the chemical step and products release. These different steps may require different conformational states of the active site that have distinct binding properties ...

Analysis of the crystal structure of an active MCM hexamer

open access: yeseLife, 2014
In a previous Research article (Froelich et al., 2014), we suggested an MCM helicase activation mechanism, but were limited in discussing the ATPase domain because it was absent from the crystal structure.
