Figure 6.
Stereoview of the succinyl-CoA radical relative to cob-(II)alamin and 5′-deoxyadenosine in the active site of MCM. X-ray coordinates from Protein Data Bank entry 4REQ were used to position atoms other than those from the succinyl radical moiety. The distance from Co2+ to C3 of the succinyl-CoA radical is 6.0 Å. The distance between C5′ of 5′-deoxyadenosine and C3 of the succinyl-CoA radical is 3.5 Å.
