Protein Variants | Comment | Organism |
---|---|---|
additional information | construction of a N-terminally truncated enzyme lacking amino acids 1-134 and a full-length mature form containing the trans-membrane domain but lacking the transit peptide. N-terminally truncated variant shows very poor activity with PsbO substrate | Arabidopsis thaliana |
S142A | very poor activity with PsbO substrate | Arabidopsis thaliana |
Inhibitors | Comment | Organism | Structure |
---|---|---|---|
arylomycin A2 | 0.01 mM, 90% inhibition | Arabidopsis thaliana | |
dithiothreitol | 90% inhibition. Enzyme contains a redox-active Cys pair and requires disulfide bond formation between them for its activity in vitro | Arabidopsis thaliana |
