Abstract

Summary: strain 206 degrades benzoate via the -cleavage pathway. In a genomic library derived from this organism a clone was obtained which carried and expressed the gene for the third enzyme in this pathway, catechol 2,3-dioxygenase (EC 1.13.11.2), on a 5.9 kb I restriction fragment. The structural gene was more precisely mapped on an internal 1.6 kb RI fragment which, after insertion into expression vectors, directed the synthesis of a 33 kDa polypeptide. The gene showed very little or no homology with isofunctional genes derived from Comprehensive substrate specificity analysis showed significant differences between the specific activities obtained from the cloned gene product and extracts derived from itself.
