Yay, one more paper is accepted: An ancient family of SelB elongation factor-like proteins with a broad but disjunct distribution across archaea. Gemma C Atkinson, Vasili Hauryliuk and Tanel Tenson, BMC Evolutionary Biology 2011, 11:22.
The nitty-gritty: we found a SelB relative which is not likely to bind and deliver selenocysteinyl-tRNA. It does something else, and we do not know what. tRNA binding domain and ribosome-binding interfaces are intact, but the G domain is messed up, so it might be a translational GTPase with no GTPase activity! For more details check out Gem's blog or... just read the paper, it is open access!
