protocatechuate 3,4-dioxygenase M-CSA #936 | Protocatechuate dioxygenase breaks open the ring of catechol by adding molecular oxygen to the bond between two hydroxyl groups. It is important in the detoxification and breakdown of aromatic compounds by bacteria. It also has a role in the pathway of phenylalanine metabolism. | Defined by 5 residues: TYR:B-108 [auth M-408]TYR:B-147 [auth M-447]ARG:B-157 [auth M-457]HIS:B-160 [auth M-460]HIS:B-162 [auth M-462] | EC: 1.13.11.3 (PDB Primary Data) |
