Orthanilic acid (2-aminobenzenesulfonic acid, (S)Ant), an aromatic β-amino acid, has been shown to be highly useful in inducing a folded conformation in peptides. When incorporated into peptide sequences (Xaa-(S)Ant-Yaa), this rigid aromatic β-amino acid strongly imparts a reverse-turn conformation to

Alcaligenes sp. strain O-1 utilizes three sulphonated aromatic compounds as sole sources of carbon and energy for growth in minimal salts medium-benzenesulphonate (BS), 4-toluenesulphonate (TS) and 2-aminobenzenesulphonate (2AS). The degradative pathway(s) in 2AS-grown cells are initiated with membrane transport, NADH-dependent

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
