Reconstitution of apo-yDbr1 with Fe2+, Zn2+, and Mn2+. (A) Apo-yDbr1 (1 µM) was reconstituted with 0–100 µM of the indicated metals under anaerobic conditions. Apo-yDbr1, black diamonds at metal = 0, had no detectable activity without exogenous metals. (B) Results of curve fitting to obtain estimates of kcat and Kmetal.
