摘要： Provided is a novel cis-aconitate synthesis enzyme, more particularly, a recombinant microorganism for producing itaconate including a cis-aconitate synthesis enzyme variant. According to the present disclosure, it was confirmed that the production and yield of itaconate were significantly increased in the recombinant microorganism for producing itaconate into which the novel cis-aconitate synthesis enzyme was introduced. In addition, it was confirmed that in the recombinant microorganism for producing itaconate of the present disclosure, a new carbon flow to itaconate was separated from the existing TCA cycle based on the activity of the corresponding enzyme. Accordingly, the novel aconitate synthesis enzyme of the present disclosure and the recombinant microorganism introduced with the aconitate synthesis enzyme can increase the economic feasibility of itaconate, and thus can be used in various industrial fields, such as synthetic resins, latexes, and food additives in which itaconate is used.
