The arrowheads indicate the CD spectra of the respective protein. () Intrinsic fluorescence spectra of wild-type and different deletion mutants. The fluorescence emission spectra of wild-type and different mutant forms of HpDnaB (as indicated) were recorded from 300 to 400 nm at 25°C. The excitation wavelength was 278 nm and data were collected at 0.5 nm wavelengths resolution. The arrowheads indicate the CD spectra of the respective protein.
