The enzyme catalysing the reduction of maleylacetate to 3-oxoadipate was purified 150-fold from Trichosporon cutaneum, induced for aromatic metabolisms by growth with resorcinol as a major carbon source. The enzyme separated upon electrofocusing into three species with PI values 4.6, 5.1 and 5.6. They had similar catalytic properties and the same molecular weight.
以间苯二酚作为主要碳源培养,可诱导皮肤毛孢子菌产生芳香族代谢酶,该酶可催化马来酰乙酸还原为3-氧代己二酸,从皮肤毛孢子菌中纯化得到的该酶比活性提高了150倍。该酶经等电聚焦分离为三种,其PI值分别为4.6、5.1和5.6。它们具有相似的催化特性和相同的分子量。
