Synthesis Activity

Enterobacter cancerogenus strain M004 genome size is 5.67 Mb. Here, its luxI homologue, designated as ecnI which is ecnI gene (633 bp) was cloned and overexpressed. Its AHL synthesis activity was verified using the high-resolution liquid chromatography-mass spectrometry analysis revealed the production of N-(3-oxo-hexanoyl)-L-homoserine lactone (3-oxo-C6-HSL) and N-(3-oxo-hexanoyl)-L-homoserine lactone (3-oxo-C8-HSL). The cloning and characterization of luxI homologue of E. cancerogenus strain M004 was firstly reported here.
