WebAlthough this is not a heme binding protein per se, it does bind a linear tetrapyrrole pigment derived from heme. Heme binds between two a-helices, coordinated to histidine, in proteins as diverse as lignin peroxidase (32) and cytochrome b562 (33), but the topology of these helices differs from the globin fold.
