Phenol monooxygenase (PMO) and catechol 1,2-dioxygenase (C12O), the two first enzymes of the phenol-degradation pathways, are encoded by a 3.4-kb DNA fragment cloned from Pseudomonas sp. EST1001 plasmid DNA. We have previously shown that activation of the cloned genes in Pseudomonas putida PaW85 is controlled by insertion of the 17-kb transposon, Tn4652, from the host chromosome into the plasmid carrying these genes [Kivisaar et al. Plasmid 24 (1990) 25-36]. Transcription of the DNA encoding PMO (pheA) and C12O (pheB) is activated by a promoter located on a 0.2-kb SacI-ClaI fragment from Tn4652. We have determined the nucleotide sequence of pheB. The 906-bp gene encodes a protein product with a deduced Mr of 33,362. The relationship between the pheB gene and other C12O-encoding genes has been shown: comparison of the pheB sequence with sequences of catA of Alcaligenes calcoaceticus, tfdC of A. eutrophus and clcA of P. putida demonstrated that there are conserved residues in all the four protein products of these genes.
