title: Haloferax volcanii UbaA, catalytic engine for sampylation and sulfur transfer.
abstract: The Small Archaeal Modifier Proteins (SAMPs) from Haloferax volcanii belong to the group of ubiquitin like proteins (Ubls) that act both as protein modifiers and sulfur carriers. The E1-like enzyme UbaA is essential for SAMP activation and therefore required for both sampylation and sulfur transfer. Here, we provide a commentary on the thorough characterization of UbaA by J. Maupin-Furlow and colleagues.
