Roles Classification
Biological Role(s): metabolite
Any intermediate or product resulting from metabolism. The term 'metabolite' subsumes the classes commonly known as primary and secondary metabolites.
EC 5.99.1.2 (DNA topoisomerase) inhibitor
A topoisomerase inhibitor that inhibits the bacterial enzymes of the DNA topoisomerases, Type I class (EC 5.99.1.2) that catalyze ATP-independent breakage of one of the two strands of DNA, passage of the unbroken strand through the break, and rejoining of the broken strand. These bacterial enzymes reduce the topological stress in the DNA structure by relaxing negatively, but not positively, supercoiled DNA.
plant metabolite
Any eukaryotic metabolite produced during a metabolic reaction in plants, the kingdom that include flowering plants, conifers and other gymnosperms.
