Fig. 3. Structural overlay of the globin domains of E. coli and A. eutrophus flavohemoglobin and Vitreoscilla sp. hemoglobin. The overlay among globin domains was obtained by minimizing the C- distances for each protein using the program SEQUOIA (21) and was depicted with the program MOLSCRIPT (28). The stereo diagram of the globin domain of HMP ( red ribbons, yellow heme) is overlaid with the corresponding domain of A. eutrophus flavohemoglobin (green ribbons, green heme) in A and with Vitreoscilla Hb (cyan ribbons, blue heme) in B.
