2-Aminobenzenesulfonamide

F Junker et al.
The Biochemical journal, 300 ( Pt 2), 429-436 (1994-06-01)
2-Aminobenzenesulphonic acid (2AS) is degraded by Alcaligenes sp. strain O-1 via a previously detected but unidentified intermediate. A mutant of strain O-1 was found to excrete this intermediate, which was isolated and identified by m.s., 1H- and 13C-n.m.r. as 3-sulphocatechol
Jürgen Ruff et al.
Microbiological research, 165(4), 288-299 (2009-07-07)
Alcaligenes sp. strain O-1 inducibly deaminates 2-aminobenzenesulfonate (ABS) 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 (Scm). The complete pathway is encoded on the

A unique strategy for synthesis of narrowly distributed and inherently self-stabilized copolymer nanoparticles by a simple emulsifier-free polymerization from orthanilic acid and aniline was developed. The polymerization yield, electrical conductivity, size, and its distribution of the nanoparticles could be simultaneously
