Pseudomonas paucimobilis Q1 originally isolated as biphenyl degrading organism (Furukawa et al. 1983), was shown to grow with naphthalene. After growth with biphenyl or naphthalene the strain synthesized the same enzyme for the ring cleavage of 2,3-dihydroxybiphenyl or 1,2-dihydroxynaphthalene. The enzyme, although characterized as 2,3-dihydroxybiphenyl dioxygenase (Taira et al. 1988), exhibited considerably higher relative activity with 1,2-dihydroxynaphthalene. These results demonstrate that this enzyme can function both in the naphthalene and biphenyl degradative pathway.
少动假单胞菌Q1最初作为联苯降解菌被分离出来（Furukawa等人，1983年），已证明它能以萘为底物生长。在以联苯或萘生长后，该菌株合成了相同的用于2,3-二羟基联苯或1,2-二羟基萘环裂解的酶。尽管该酶被鉴定为2,3-二羟基联苯双加氧酶（Taira等人，1988年），但它对1,2-二羟基萘表现出相当高的相对活性。这些结果表明，这种酶在萘和联苯降解途径中都能发挥作用。
