| Outline of Final Research Achievements |
Pigments are produced from numerous bacterial species. Although several pigments possess hemolytic and cytotoxic properties, their roles in virulence of bacterial pathogens is not fully appreciated. In this study, we found that GNAT (GCN5-related N-acetyltransferase) is related to ornithine rhamnolipid-like pigment synthesis of Propionibacterium acnes. Moreover, we demonstrated that the pigmentation is responsible for their hemolytic activity. P. acnes is known to be associated with sarcoidosis. Our results suggest that targeting of P. acnes pigment could serve as a novel strategy to treatment for sarcoidosis.
