Abstract excerpt
Heme binding to cytochrome b6 is resistant, in part, to denaturing conditions that typically destroy the noncovalent interactions between the b hemes and their apoproteins, suggesting that one of two b hemes of holocytochrome b6 is tightly bound to the polypeptide. We exploited this property to define a pathway for the conversion of apo- to holocytochrome b6, and to identify mutants that are blocked at one step...
