The pheB gene from Geobacillus stearothermophilus DSM6285 has been exploited as a reporter gene for Geobacillus spp. The gene product, catechol 2,3-dioxygenase (C23O), catalyzes the formation of 2-hydroxymuconic semialdehyde, which can be readily assayed. The reporter was used to examine expression from the ldh promoter associated with fermentative metabolism.

D050557	Catechol 2,3-Dioxygenase	Catalyzes the oxidation of catechol to 2-hydroxymuconate semialdehyde in the carbazole and BENZOATE degradation via HYDROXYLATION pathways. It also catalyzes the conversion of 3-methylcatechol to cis, cis-2-hydroxy-6-oxohept-2,4-dienoate in the TOLUENE and XYLENE degradation pathway. This enzyme was formerly characterized as EC 1.13.1.2.	3-Sulfocatechol 2,3-Dioxygenase,Catechol-2,3-Dioxygenase,Metapyrocatechase,Pyrocatechol-2,3-Oxygenase,2,3-Dioxygenase, 3-Sulfocatechol,2,3-Dioxygenase, Catechol,3 Sulfocatechol 2,3 Dioxygenase,Catechol 2,3 Dioxygenase,Pyrocatechol 2,3 Oxygenase
