Short summary
Natural photosynthetic reaction centers (RCs) are built up by two parallel branches of cofactors. While photosystem II and purple bacterial RCs selectively use one branch for light-driven electron transfer, photosystem I, as also shown here, is using both branches. Comparing NMR chemical shifts, we shown that the two donor cofactors in photosystem I are similarly distinguished to those in purple bacterial RCs (Schulten et al., 2002; Biochemistry 41, 8708). Alternative reasons are discussed.
