4-Methoxygentisic acid was an intermediate formed when Arthrobacter degraded, 2,4,5-trimethoxybenzoic acid. Isolates of Pseudomonas and Arthrobacter from soil grew at the expense of 3-methoxycrotonic acid. Evidence is presented that enzymatic hydration, with elimination of methanol, accounted for replacement of the methoxyl group of 3-methoxycrotonic acid and also of one methoxyl group of 2,4,5-trimethoxybenzoic acid.
4-甲氧基龙胆酸是节杆菌降解2,4,5-三甲氧基苯甲酸时形成的一种中间体。从土壤中分离出的假单胞菌和节杆菌菌株能够以3-甲氧基巴豆酸为代价生长。有证据表明,酶促水合作用伴随着甲醇的消除,这解释了3-甲氧基巴豆酸的甲氧基以及2,4,5-三甲氧基苯甲酸的一个甲氧基被取代的原因。
