Heme, a complex of iron and protoporphyrin IX, plays an essential role in numerous biological processes including oxygen transport, oxygen storage, and electron transfer. The role of heme as a prosthetic group in bacterial hemoprotein gas sensors, which utilize heme as a cofactor for the binding of diatomic gas molecules, has been well studied. Less well known is the role of protein sensors of heme. In this report, we characterize the heme binding properties of a phosphodiesterase, CdpA, from Vibrio cholerae. We demonstrate that the
