Cinnamoyl lipids as novel signaling molecules modulate the physiological metabolism of cross-phylum microorganisms.

ABSTRACT: Signaling systems of microorganisms are responsible for regulating the physiological and metabolic processes and also play vital roles in the communications of cells. Identifying signaling molecules mediating the cross-talks is challenging yet highly desirable for comprehending the microbial interactions. Here, we demonstrate that a pathogenic Gram-negative Chromobacterium violaceum exerts significant influence on the morphological differentiation and secondary metabolism of Gram-positive Streptomyces. The physiological metabolisms are directly modulated by three novel cinnamoyl lipids (CVCL1, 2, and 3) from C. violaceum CV12472, whose biosynthesis is under the control of N-acylhomoserine lactone signaling system. Furthermore, a receptor of CVCLs in Streptomyces ansochromogenes 7100 is det
