  • Title: Cloning of cmpE, a plasmid-borne catechol 2,3-dioxygenase-encoding gene from the aromatic- and chloroaromatic-degrading Pseudomonas sp. HV3.

    Journal: Gene; 1994 Jan 28; 138(1-2):119-21. PubMed ID: 8125288.
    Abstract:
    Pseudomonas sp. strain HV3 degrades aromatics and chloroaromatics. It harbours a mega-plasmid, designated pSKY4, from which the gene cmpE, encoding a catechol 2,3-dioxygenase (C23O) catalyzing the conversion of catechol to 2-hydroxymuconic semialdehyde, was cloned and sequenced. The deduced amino acid (aa) sequence shows the highest homology, 52%, to the deduced aa sequences of xylE1 and dmpB. The deduced 307-aa sequence of cmpE contains the extradiol ring-cleavage signature in the same position as other 307-aa C23O-encoding genes.
