N-(3-Oxobutanoyl)-L-homoserine lactone (3-oxo-C4-HSL) is a carbapenem antibiotic biosynthesis autoregulator in Erwinia carotovora ATCC 39048. N-(3-Oxobutanoyl)-L-homoserine lactone induces expression of rhiI in R. leguminosarum[1].

ChEBI: N-(3-oxo-butanoyl)-homoserine lactone is a N-acyl-amino acid.

N-3-oxo-butyryl-L-Homoserine lactone is a bacterial quorum-sensing signaling molecule.1 It induces expression of rhiI in R. leguminosarum, a gene with roles in the interaction of the rhizosphere with legumes.
