Description

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 [PMID: 10712553, PMID: 11132635]. Optimal activity of sulfite reductase (SiR) is essential for normal growth in Arabidopsisis [PMID: 20424176].
