Phylogenomic analysis of proteins that are distinctive of Archaea and its main subgroups and the origin of methanogenesis

BMC Genomics, 2007
Background The Archaea are highly diverse in terms of their physiology, metabolism and ecology. Presently, very few molecular characteristics are known that are uniquely shared by either all archaea or the different main groups within archaea.

Cbp1 and Cren7 form chromatin-like structures that ensure efficient transcription of long CRISPR arrays

Nature Communications
CRISPR arrays form the physical memory of CRISPR adaptive immune systems by incorporating foreign DNA as spacers that are often AT-rich and derived from viruses. As promoter elements such as the TATA-box are AT-rich, CRISPR arrays are prone to harbouring

Archaea express circular isoforms of IS200/IS605-associated ωRNAs

Frontiers in Microbiology
Circular RNAs (circRNAs) are RNA molecules with 5′ and 3′ ends covalently ligated. Their functions range from acting as genetic regulators to producing proteins, and they are often expressed in a tissue and condition-specific manner.

A relay race of ESCRT-III paralogs drives cell division in a hyperthermophilic archaeon

mBio
Cell division is a fundamental process ensuring the perpetuation of all cellular life forms. Archaea of the order Sulfolobales divide using a simpler version of the eukaryotic endosomal sorting complexes required for transport (ESCRT) machinery, composed
