1.7.7.1	p-chloromercuribenzoate	not	43	
1.7.7.1	p-hydroxymercuribenzoate	enzyme from higher plants and eukaryotic algae inhibited, cyanobacterial enzyme not	98	
1.7.7.1	p-hydroxymercuribenzoate	-	98	
1.7.7.1	Phenyl mercury acetate	-	94716	
1.7.7.1	Phenylglyoxal	inhibits the ability of the enzyme to form a high-affinity complex with ferredoxin by modifying arginine residues	301	
1.7.7.1	Phenylglyoxal	loss of enzymatic activity when reduced ferredoxin serves as electron donor, but very little effect with methyl viologen as electron donor, ferredoxin protects the enzyme	301
