目的：表达甲苯邻二甲苯单加氧酶(Tomo)的重组南极盐生假单胞菌TAC125(P.haloPlatraktis TAC/Tou)能在较宽的温度范围内有效地将几种芳香族化合物转化为相应的儿茶酚。当在电子计算机上分析嗜盐假单胞菌TAC125的基因组时，发现了编码一种可能的漆酶样蛋白的DNA序列。众所周知，细菌漆酶能够氧化双氧芳烃化合物，如儿茶酚。
Aims: The recombinant Antarctic Pseudoalteromonas haloplanktis TAC125 (P. haloplanktis TAC/tou) expressing toluene‐o‐xylene monooxygenase (ToMO) can efficiently convert several aromatic compounds into their corresponding catechols in a broad range of temperature. When the genome of P. haloplanktis TAC125 was analysed in silico, the presence of a DNA sequence coding for a putative laccase‐like protein was revealed. It is well known that bacterial laccases are able to oxidize dioxygenated aromatic compounds such as catechols.
