Chain A (Q8GGK7_GEOSN | Q8GGK7)

molecular function
	GO:0009055	electron carrier activity	Any molecular entity that serves as an electron acceptor and electron donor in an electron transport chain. An electron transport chain is a process in which a series of electron carriers operate together to transfer electrons from donors to any of several different terminal electron acceptors to generate a transmembrane electrochemical gradient.
	GO:0020037	heme binding	Interacting selectively and non-covalently with heme, any compound of iron complexed in a porphyrin (tetrapyrrole) ring.
	GO:0046872	metal ion binding	Interacting selectively and non-covalently with any metal ion.
biological process
	GO:0006791	sulfur utilization	A series of processes that forms an integrated mechanism by which a cell or an organism detects the depletion of primary sulfur sources and then activates genes to scavenge the last traces of the primary sulfur source and to transport and metabolize alternate sulfur sources. The utilization process begins when the cell or organism detects sulfur levels, includes the activation of genes whose products detect, transport or metabolize sulfur-containing compounds, and ends when the sulfur is incorporated into the cell or organism's metabolism.
