An Asgard archaeon from a modern analog of ancient microbial mats
It has been proposed that eukaryotic cells evolved via symbiosis between sulfate-reducing bacteria and hydrogen-producing archaea. Here we describe a highly enriched culture of a novel Asgard archaeon...

Our recent study analyzes the archaeal SRP system, focusing on the FtsY protein's N-terminal domain. This work highlights the key role of the A domain and N-terminal alpha helices in generating the functional TC in archaea.

What is the role of MinD proteins in Archaea? They are not involved in positioning of the cell division proteins, but might rather position the archaellum machinery at the poles and interact with cytosceletal proteins. New paper alert coming!
