Abstract: The present invention relates to a promoter system inducing expression of 3-hydroxypropionic acid (3-HP) and a method of biologically producing 3-HP using the same. To improve production of 3-HP in a biological manner, continuous synthesis of new enzymes having enzyme activity is necessary. As a result of screening 3-HP reactive transcription regulators and 3-HP reactive promoters from several microorganisms including Pseudomonas denitrificans, it was confirmed that the transcriptions regulations and promoters are composed of LysR proteins and particular gene nucleotide sequences binding to the LysR proteins. Therefore, the 3-HP inducible system is expected to be effectively used to regulate 3-HP metabolic pathways.
