Abstract

Pseudomonas putida NCIB 10015 metabolizes phenol and the cresols (methylphenols) by the meta pathway and metabolizes benzoate by the ortho pathway. Growth on catechol, an intermediate in the metabolism of both phenol and benzoate, induces both ortho and meta pathways; growth on 3- or 4-methylcatechols, intermediates in the metabolism of the cresols, induces only the meta pathway to a very limited degree. Addition of catechol at a growth-limiting rate induces virtually no meta pathway enzymes, but high levels of ortho pathway enzymes. The role of catechol and the methylcatechols as inducers is discussed. A method is described for assaying low levels of catechol 1,2-oxygenase in the presence of high levels of catechol 2,3-oxygenase and vice versa.

摘要

恶臭假单胞菌NCIB 10015通过间位途径代谢苯酚和甲酚(甲基苯酚),并通过邻位途径代谢苯甲酸。在儿茶酚(苯酚和苯甲酸代谢的中间产物)上生长会诱导邻位和间位途径;在3-或4-甲基儿茶酚(甲酚代谢的中间产物)上生长仅在非常有限的程度上诱导间位途径。以生长限制速率添加儿茶酚几乎不诱导间位途径酶,但会诱导高水平的邻位途径酶。讨论了儿茶酚和甲基儿茶酚作为诱导剂的作用。描述了一种在存在高水平儿茶酚2,3-加氧酶的情况下测定低水平儿茶酚1,2-加氧酶的方法,反之亦然。
