Abstract
Sulphite reductase (ferredoxin) is a cyanobacterial and plant monomeric enzyme distantly related to the iron-sulphur hemoprotein of sulphite reductase (NADPH) found in Proteobacteria and Eubacteria that also catalyses the reduction of sulphite to sulphide [ 1 , 2 ]. Optimal activity of sulfite reductase (SiR) is essential for normal growth in Arabidopsisis [ 3 ].
