2-aminobenzenesulfonate is used in the manufacture of dyes and pharmaceuticals, and, typical of xenobiotic aryl-sulfonates. The compound is degraded in few native environments, e.g. by Alcaligenes sp. strain O-1, the overall degradative process for ABS in strain O-1 is complex, overview. The pathway shows both split operons and dispersed pathway genes, and no transcriptional regulator

AbsAa, enzyme component; DSM 6325, six genes of the abs cluster are co-transcribed and contain the genes for two subunits of the oxygenase component of the ABS-dioxygenase system
AbsAb, enzyme component; DSM 6325, six genes of the abs cluster are co-transcribed and contain the genes for two subunits of the oxygenase component of the ABS-dioxygenase system
Alcaligenes sp. O-1 inducibly deaminates 2-aminobenzenesulfonate via dioxygenation to 3-sulfocatechol, which is desulfonated during meta ring-cleavage to yield 2-hydroxymuconate. This intermediate is transformed through the oxalocrotonate-branch of the sulfocatechol meta-pathway, overview. The pathway shows both split operons and dispersed pathway genes, and no transcriptional regulator, overview.
