Distal Cleavage of 3-Chlorocatechol by an Extradiol Dioxygenase to 3-Chloro-2-Hydroxymuconic Semialdehyde

A 2,3-dihydroxybiphenyl 1,2-dioxygenase from the naphthalenesulfonate-degrading bacterium Sphingomonas sp. strain BN6 oxidized 3-chlorocatechol to a yellow product with a strongly pH-dependent absorption maximum at 378 nm. A titration curve suggested (de)protonation of an ionizable group with a pK(a...
