(a) The core structure of the E. coli RNA helicase DbpA. The conserved and functional protein domains are highlighted in blue, purple, red, yellow, brown and light blue. Mg2+ (designated as a brown sphere) is bound to ATP (green). (b) Mn K-edge spectra of Mn-substituted DbpA bound to ATPγ S, ADP, RNA-ATPγ S and RNA-ADP. (c) Expended view of the pre-edge spectra of (b) (6544–6552 eV).
