MbtH-like proteins are a family of small proteins encoded by genes found in many, but not all, non-ribosomal peptide synthetase-encoding gene clusters that direct the biosynthesis of peptide antibiotics and siderophores. Studies published to date have not elucidated the function of MbtH-like proteins, nor have they clarified whether they are required for metabolite biosynthesis. Here it is shown that only one of two genes (cdaX or cchK) encoding MbtH-like proteins in Streptomyces coelicolor is required for biosynthesis of the peptide siderophore coelichelin and the calcium-dependent peptide antibiotic (CDA). The cdaX and cchK genes can functionally complement each other in trans, suggesting that CdaX and CchK can cross-talk with the coelichelin and CDA biosynthetic pathways, respectively. Transcriptional analyses of wild-type S. coelicolor and a double cchK/cdaX replacement mutant indicate that CchK and CdaX may not be involved in transcriptional regulation of coelichelin and CDA biosynthetic gene clusters.
