GO
GO:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. GO:0015232 Enables the transfer of heme from one side of a membrane to the other. GO:0015886 The directed movement of heme, any compound of iron complexed in a porphyrin (tetrapyrrole) ring, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. GO:0017004 The aggregation, arrangement and bonding together of a cytochrome complex. A cytochrome complex is a protein complex in which at least one of the proteins is a cytochrome, i.e. a heme-containing protein involved in catalysis of redox reactions. GO:0005886 The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. GO:1903607 The chemical reactions and pathways resulting in the formation of cytochrome c.
