The University of Minnesota Biocatalysis/Biodegradation Database (UM/BBD) contains "microbial biocatalytic reactions and biodegradation pathways primarily for xenobiotic, chemical compounds." A new microbial enzyme-catalyzed reactions has been posted for 2,4-Dichlorophenoxyacetic Acid. 2,4-dichlorophenoxyacetic acid (2,4-D) is used in cultivated agricultural areas, rangeland and pastures, forests, and homes or gardens, and is "a chlorinated phenoxy compound [that] functions as a systemic herbicide and is used to control many types of broadleaf weeds." The degradation pathway map includes organisms which can initiate the pathway. The pathway map provides detailed information on each hyperlinked step, including graphics, product/substrate reactions, and external links to further information.
