Figure 7

Model of the active site of MCM showing the position of the succinyl-CoA radical relative to cob(II)alamin and the inferred g-axis system of the low-spin Co2+ in the molecule. Euler angles (ζ 50° and η = 33°) are also shown. The faded image of the succinyl-CoA represents the position from X-ray coordinates (PDB entry 4REQ) (31).
