General Information | Comment | Organism |
---|---|---|
metabolism | the alpha8beta4 SiR holoenzyme assembles through the N-terminus of flavin-binding flavoprotein SiRFP and the NADPH binding domain of iron-containing hemoprotein SiRHP. Apo-SiRHP forms a homotetramer, also dependent on its N-terminus, that is unable to assemble with SiRFP | Escherichia coli |
