Asymmetric/Biological Unit(hide GO term definitions)

Chain A (Q6XCI5_DESBA | Q6XCI5)


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.
