Figure 3From: The prokaryotic antecedents of the ubiquitin-signaling system and the early evolution of ubiquitin-like β-grasp domainsDomain architectures of ThiS/MoaD-like ubiquitin domains and functionally associated proteins. Architectures belonging to a particular gene neighborhood or related pathway are grouped in boxes. Proteins are identified below the architectures by gene name, species abbreviation and gi number, demarcated by underscores. Proteins belonging to the classical thiamine and MoCo/WCo biosynthesis pathways are shown above the purple line. Species abbreviations are listed in the legend to Figure 2. JAB-N, an α + β domain found amino-terminal to some JAB proteins; TAPI-C, domain found carboxyl-terminal to the phage λ-TAPI-like ubiquitin domain; Rhod, Rhodanese domain; X, β-strand rich, poorly conserved globular domain; ZnR, zinc ribbon domain.Back to article page
