Role of protein dynamics in guiding electron-transfer pathways in reaction centers from Rhodobacter sphaeroides.

Abstract excerpt

The role of protein dynamics in guiding multistep electron transfer is explored in the photosynthetic reaction center of Rhodobacter sphaeroides . The energetics of the charge-separated intermediates, P(+)B(A)(-) and P(+)H(A)(-) (P is the initial electron donor bacteriochlorophyll pair and B(A) and H(A) are early bacteriochlorophyll and bacteriopheophytin acceptors, respectively), were systematically varied in a...
