Most structural and biochemical diversification of the beta-GF occurred in prokaryotes, with GANT61 inhibitor the Ubl clade showing a dramatic expansion in the eukaryotic phase of its evolution. Hence, at least 70 distinct Ubl families are observed in eukaryotes, of which nearly 20 families were probably present in the last eukaryotic common ancestor. Diversification of Ubl families early in eukaryotic evolution played a major role in emergence of characteristic eukaryotic cellular sub-structures and systems pertaining to nucleo-cytoplasmic compartmentalization and dynamics, vesicular trafficking, autophagy and different protein degradation systems. Recent comparative genomics studies indicate that precursors of the eukaryotic Ub-system emerged first in prokaryotes. The simplest of these combine an Ubl and an E1-like enzyme involved in metabolic pathways related metallopterin, thiamine, cysteine, siderophore and perhaps modified base biosynthesis. Sampylation in archaea and Urmylation in eukaryotes appear to represent direct recruitment of such systems as simple protein-tagging apparatuses. However, other prokaryotic systems incorporated further components that more or less mirror the eukaryotic condition in possessing an E2, a RING-type E3 or both of these components. Additionally, prokaryotes have evolved conjugation systems that are independent of Ub ligases, such as the Pup program. ((firmicutes) cell surface area virulence proteins??PDB: 1HEZ, several othersE.
