7.1.1.6	heme	atypical as it is covalently bound by one thioether linkage and has no axial amino acid ligand	659999	
7.1.1.6	heme	contains four hemes	675127	
7.1.1.6	heme	cytochrome b6 subunit of the cytochrome b6f complex is a multiheme protein. Two b-type hemes are bound non-covalently to the protein, whereas the third heme (heme cn) is covalently attached via an atypical thioether bond. HCF208, a homolog of Chlamydomonas CCB2, is required for accumulation of native cytochrome b6 in Arabidopsis thaliana	689491
