Abstract

Some of the Beneckea harveyi dim aldehyde mutants, all of which emit light upon addition of exogenous long-chain aldehyde, also emit light when myristic acid is added. Analysis of these myristic acid-responsive mutants indicates that they are blocked before fatty acid formation, whereas another class of mutants, which respond only to aldehyde, appear to be defective in the enzyme(s) involved in the conversion of acid to aldehyde. Evidence is presented that this activity, designated myristic acid reductase, is coinduced with luciferase and is involved in the recycling of acid produced in the luciferase reaction, with specificity for the C14 compounds.

摘要

一些哈维贝内克氏菌二醛突变体,在添加外源长链醛时都会发光,当添加肉豆蔻酸时也会发光。对这些肉豆蔻酸响应突变体的分析表明,它们在脂肪酸形成之前就被阻断了,而另一类仅对醛有反应的突变体,似乎在参与酸转化为醛的酶方面存在缺陷。有证据表明,这种被称为肉豆蔻酸还原酶的活性与荧光素酶共同诱导,并参与荧光素酶反应中产生的酸的循环利用,对C14化合物具有特异性。
