The central component of the cluster machinery is a scaffold protein which mobilizes sulfur atoms from a cysteine desulfurase and iron atoms from an iron donor to synthesize a [2Fe–2S] or a [4Fe–4S] cluster. Subsequently, the latter are transferred to an apo-protein target.

WebMay 30, 2014 · The reaction of sulfide with iron (III) conceals the formation of sulfide, effectively recycling sulfur for multiple rounds of microbial reduction. Thus, a microbially catalyzed hidden or “cryptic” sulfur cycle (see the image) operates at alkaline pH. In alkaline aquifers, sulfur-reducing bacteria require a source of sulfur.
