Six of the eight cysteine residues are clustered as Cys-Pro-Cys and Cys-His-Cys groups. Cysl9 and Cys27 are free cysteines with no catalytic function, Cys54 and Cys84 constitute the redox-active disulfide bridge of the active site, and the remaining four, Cys52, Cys71, Cys73, and Cys82 bind the Fe-S cluster 703527 1.8.7.2 additional information amino acid sequence of the variable subunit, without known catalytic function. the n-terminal consensus domain is possible involved in the interaction with the catalytic subunit 703528 1.8.7.2 additional information protein modulase is a complex protein composed of ferredoxin/thioredoxin reductase, ferredoxin, and thioredoxin. Buffer ionic strength affects the interactions among these proteins and in part determines the fate of the protein modulase complex in vitro. The ferredoxin and thioredoxin active in light modulation are not free in solution 706339
