ABC-type transporter; part of the gene cluster that mediates the biosynthesis of cichorine, a phytotoxin active against knapweed, corn, and soybeans (PubMed:24244835). CicA is probably involved in the secretion of cichorine (Probable). Abolishes the production of cichorine. Cichorine and its derivatives are promising in the course of developing novel herbicides. Belongs to the ABC transporter superfamily. ABCC family. Conjugate transporter (TC 3.A.1.208) subfamily.
