CRYSTAL STRUCTURE OF WILD-TYPE PROTOCATECHUATE 3,4-DIOXYGENASE FROM ACINETOBACTER SP. ADP1 IN COMPLEX WITH CATECHOL


Overview

The catechol dioxygenases allow a wide variety of bacteria to use aromatic compounds as carbon sources by catalyzing the key ring-opening step. These enzymes use specifically either catechol or protocatechuate (2,3-dihydroxybenozate) as their substrates; they use a bare metal ion as the sole cofactor. To learn how this family of metalloenzymes functions, a structural analysis of designed and selected mutants of these enzymes has been undertaken. Here we review the results of this analysis on the nonheme ferric iron intradiol dioxygenase protocatechuate 3,4-dioxygenase.
