Abstract excerpt
PsaC-C14D (cysteine 14 replaced by aspartic acid) contains a [3Fe-4S] and a [4Fe-4S] cluster in the FB and FA sites of the free protein [Yu, L., Zhao, J., Lu, W., Bryant, D. A., & Golbeck, J. H. (1993) Biochemistry 32, 8251-8258]. When PsaC-C14D is rebound to a photosystem I (PS I) core, the g-va...
