Protein
Ergochrome gene cluster transcriptional coactivator CPUR_05432
Organism
Claviceps purpurea (strain 20.1)
Function
Transcriptional coactivator; part of the gene cluster responsible for the typical purple-black color of the ergot sclerotia (PubMed:28955461). The ergochrome gene cluster produces several ergot pigments including the yellow ergochrome secalonic acid and its derivatives, as well as the red anthraquinones endocrocin and clavorubin (PubMed:28955461). With CPUR_05433, coregulates the production of geodin (PubMed:28955461).
