Catalysis of the reaction: ATP + H2O + heme(in) = ADP + phosphate + heme(out). Primary active transport of a solute across a membrane, driven by the hydrolysis of the diphosphate bond of inorganic pyrophosphate, ATP, or another nucleoside triphosphate. The transport protein may or may not be transiently phosphorylated, but the substrate is not phosphorylated. Primary active transport is catalysis of the transport of a solute across a membrane, up the solute's concentration gradient, by binding the solute and undergoing a series of conformational changes. Transport works equally well in either direction and is driven by a primary energy source. Enables the directed movement of a cofactor into, out of, within or between cells. A cofactor is a substance that is required for the activity of an enzyme or other protein. Enables the directed movement of heme, any compound of iron complexed in a porphyrin (tetrapyrrole) ring, into, out of, within or between cells. Catalysis of the reaction: ATP + H2O = ADP + phosphate to directly drive the active transport of a substance across a membrane. Catalysis of the hydrolysis of an acid anhydride to directly drive the transport of a substance across a membrane. Catalysis of the reaction: ATP + H2O = ADP + phosphate to directly drive the transport of a substance.
