This domain is found at the N-terminal end of PaaA from Enterobacter agglomerans, an enzyme involved in post-translational modification and host immunity. PaaA is composed of two domains: Pfam:PF00899 and the domains represented by this entry, which folds into a globular domain and has similarity to RiPP precursor peptide recognition elements or RREs [1].	Domain
A, B	PF00899	ThiF family (ThiF)	ThiF family	This domain is found in ubiquitin activating E1 family and members of the bacterial ThiF/MoeB/HesA family. It is repeated in Ubiquitin-activating enzyme E1 [1-3].	Domain
