4-Oxalocrotonate tautomerase from Pseudomonas putida mt-2 and 5-(carboxymethyl)-2-hydroxymuconate isomerase from Escherichia coli C catalyze the same reaction on substrates that differonly by a carboxymethyl group. While the structural resemblances between the substrates for these two proteins suggest that the enzymes might be evolutionarily related, the existing literature does not indicate an obvious
来自恶臭假单胞菌 mt-2 的 4-草酰巴豆酸互变异构酶和来自大肠杆菌 C 的 5-(羧甲基)-2-羟基粘康酸异构酶在仅羧甲基不同的底物上催化相同的反应。虽然这两种蛋白质的底物之间的结构相似性表明这些酶可能在进化上相关,但现有文献并未表明存在明显的联系。发现这两种酶都使 2-羟基粘康酸 (1) - 4-草酰巴豆酸互变异构酶的底物酮化
