    Cytochrome P450 from thermoacidophilic crenarchaeon, Sulfolobus tokodaii strain 7 (P450st) has been expressed in Escherichia coli and purified at high homogeneity. P450st was crystallized in an orthorhombic system with the space group P2(1)2(1)2(1) and cell dimensions of a=53.6 A, b=55.1 A, and c=130.9 A, and the structure was determined at a 3.0 A resolution. The final R-factor was 0.194 (Rfree=0.235). Structural comparison with cytochrome P450 from S. solfataricus (CYP119) suggests that the region composed of the F to G helices and the Cl- binding site is responsible for the affinity for a ligand coordinating heme iron. Direct electrochemistry of P450st in a didodecyldimethylammonium bromide (DDAB) film on a plastic formed carbon (PFC) electrode has also been demonstrated. A quasi-reversible redox response has been observed even at elevated temperatures of up to 80 degrees C.
