The prodiginines are a family of red tripyrrole pigments produced by Gammaproteobacteria as well as select Actinobacteria (e.g. Streptomyces coelicolor). It is named after prodigiosin (prodiginine). They are synthesized through a common set of enzymes. They are interesting due to their immunosuppressive and anti-cancer activities.[1]
