Deduced amino acid sequence of E. coli EutA (A) and fragmentary sequence homology between reactivating factors and Hsp70 family molecular chaperones (B). Positions that show fragmentary homology in panel B are underlined in panel A. Identical and similar amino acid residues are indicated by asterisks and dots, respectively, in panel B. Eco, E. coli; Kox, K. oxytoca; Kpn, K. pneumoniae; Cco, Clostridium cochlearium; hum, human.
