Production and purification of salicylate monooxygenase from Pseudomonas cepacia ATCC 29351.
Salicylate monooxygenase (EC: 1.14.13.1) has been produced and purified from Pseudomonas cepacia ATCC 29351 which has the ability to utilise salicylate as a sole carbon source. The bacterium was grown on a defined medium containing 2% (w/v) casamino acids and 0.15% (w/v) yeast extract at 25 degrees C; salicylate monooxygenase production was induced by the presence of up to 0.7% (w/v) sodium salicylate, to a level of approximately 2% of the soluble cell protein. The enzyme was purified over 50-fold, with a recovery of about 40%, by a combination of ion exchange and hydrophobic interaction chromatography. The purified enzyme had a specific activity of 14-15 U mg-1 protein and was essentially homogeneous.
