Abstract
Co-metabolism of 3-methylcatechol, 4-chlorocatechol and 3,5-dichlorocatechol by an Achromobacter sp. was shown to result in the accumulation of 2-hydroxy-3-methylmuconic semialdehyde, 4-chloro-2-hydroxymuconic semialdehyde and 3,5-dichloro-2-hydroxymuconic semialdehyde respectively. Formation of these products indicated that cleavage of the aromatic nucleus of the substituted catechols was accomplished by a new meta-cleaving enzyme, catechol 1,6-oxygenase. This enzyme was equally active on both chloro- and methyl-substituted catechols.
摘要
无色杆菌属细菌对3-甲基邻苯二酚、4-氯邻苯二酚和3,5-二氯邻苯二酚的共代谢作用分别导致了2-羟基-3-甲基粘康酸半醛、4-氯-2-羟基粘康酸半醛和3,5-二氯-2-羟基粘康酸半醛的积累。这些产物的形成表明，取代邻苯二酚的芳环裂解是由一种新的间位裂解酶——邻苯二酚1,6-加氧酶完成的。这种酶对氯代和甲基取代的邻苯二酚均具有同等活性。
