Cloned(Commentary)

Cloned (Comment) Organism
A central part (amino acid position 268-397 of 458 residues) of the biphenyl dioxygenase large alpha subunit, BphA1, from Pseudomonas pseudoalcaligenes (strain KF707) is exchanged with the corresponding part of BphA1 from Pseudomonas putida strain KF715, to construct hybrid BphA1, BphA1 (amino acid 715-707). When expressed in Escherichia coli together with the bphA2A3A4BC genes from strain KF707, this enzyme is shown to possess activity for degrading both 1-phenylnaphthalene and 2-phenylnaphthalene.
