Domain architecture of DprA protein of selected bacteria. Central Rossmann fold (RF) is conserved and present in all DprA proteins, while the N-terminal SAM domain is common in all DprA except those of Helicobacter
pylori and Pyrococcus
furiosus. An additional C-terminal DML1 domain is present in the DprA of Deinococcus
radiodurans, Mycobacterium
tuberculosis, Rhodopseudomonas palustris, Neisseria
meningitides, Vibrio
cholera, Haemophilus
influnzae, and Synechocytosis spp.
