title: SAMPyling proteins in archaea.
abstract: For some time, post-translational small protein modifications were found only in eukaryotes; much later, such modifications were identified in some species of bacteria. The recent discovery of ubiquitin-like proteins that form polymeric chains and covalently modify proteins in archaea finally closes the evolutionary gap among the domains of life.
