More | amino acid sequence of the catalytic subunit. 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 | Spinacia oleracea |
