Abstract
Catechol 1,2-dioxygenase has been purified 46-fold from cells of Rhizobium trifolii TA1 grown on benzoate plus glucose. The dioxygenase had a molecular weight of 107,000 and a sub-unit molecular weight of 59,000. The enzyme had a K m of 2 μM for catechol and also cleaved 4-methylcatechol. The dioxygenase contained 2 g atoms of Fe3+ per mole of enzyme which could be removed by treatment with 1,10-phenanthroline, resulting in a complete loss of activity; reactivation of the enzyme occurred specifically with Fe3+.
