An expression system for the 2-hydroxybiphenyl-3-monooxygenase gene (
hbpA) from Pseudomonas azelaica HBP1 was developed based on E. coli JM
109 and the high copy vector pUCBM20. The system was used for the conv
ersion of 2,2'-dihydroxybiphenyl to 2,2',3-trihydroxybiphenyl on a pre
parative scale with a productivity of 0.06 g h(-1) l(-1). This system
also allows the biocatalytic production of various 3-aryl-, 3-alkyl-,
and 3-halo-substituted catechols. (C) 1998 Elsevier Science B.V. All r
