Characterization of a coproporphyrin-protein complex from Rhodobacter capsulatus.
Rhodobacter capsulatus strain AJB530 excretes large amounts of coproporphyrin into the culture supernatant. The coproporphyrin was precipitable with ammonium sulfate, suggesting that it was part of a macromolecular complex. Analysis of an ammonium sulfate fraction indicated that the coproporphyrin was bound to a 66-kDa protein with a pI' of 4.0. The same protein was found in the culture supernatant of the bch+ strain PAS100.
