Abstract

NAD- and glutathione-dependent formaldehyde dehydrogenase (GD-FALDH) of Paracoccus denitrificans has been purified as a tetramer with a relative molecular mass of 150 kDa. The gene encoding GD-FALDH (flhA) has been isolated, sequenced, and mutated by insertion of a kanamycin resistance gene. The mutant strain is not able to grow on methanol, methylamine, or choline, while heterotrophic growth is not influenced by the mutation. This finding indicates that GD-FALDH of P. denitrificans is essential for the oxidation of formaldehyde produced during methylotrophic growth.

摘要

反硝化副球菌的烟酰胺腺嘌呤二核苷酸(NAD)和谷胱甘肽依赖性甲醛脱氢酶(GD-FALDH)已被纯化,为一种相对分子质量为150 kDa的四聚体。编码GD-FALDH的基因(flhA)已被分离、测序,并通过插入卡那霉素抗性基因进行了突变。突变菌株不能在甲醇、甲胺或胆碱上生长,而异养生长不受该突变影响。这一发现表明,反硝化副球菌的GD-FALDH对于甲基营养生长过程中产生的甲醛氧化至关重要。
