each subunit of homodimer contains one binuclear non-heme iron active site. The reduced DELTA9-desaturase has two approximately equivalent 5-coordinate irons in a distorted square pyramidal geometry, a two-in-two-out equatorial distortion, the irons are rhombic, weakly antiferromagnetically coupled. Addition of substrate causes dramatic changes, first ion remains 5-coordinate but is distorted toward a trigonal bipyramidal structure, second iron changes to 4-coordinate |
