The ubiquitous use of heme in animals poses severe biological and chemical challenges. Free heme is toxic to cells and is a potential source of iron for pathogens. For protection, especially in ...
Researchers described for the first time the structure of a bifunctional protein, called CcsBA, that transports heme and attaches it to cytochromes. The study captured two conformational states of ...
