Role and substrate specificity of the Streptomyces coelicolor RedH enzyme in undecylprodiginine biosynthesis

The function of RedH from Streptomyces coelicolor as an enzyme that catalyses the condensation of 4-methoxy- 2,2'- bipyrrole-5- carboxaldehyde (MBC) and 2-undecylpyrrole to form the natural product undecylprodiginine has been experimentally proven, and the substrate specificity of RedH has been probed in vivo by examining its ability to condense chemically-synthesised MBC analogues with 2-undecylpyrrole to afford undecylprodiginine analogues.
