Catabolism of taurine in Pseudomonas aeruginosa.

Cell-free extracts of taurine-grown Pseudomonas aeruginosa catalyze the transamination of taurine and pyruvate resulting in the formation of L-alanine and sulfoacetaldehyde. The enzyme responsible for this activity has been partially purified in order to demonstrate its participation in a pathway of taurine degradation. Ethyl methane sulfonate treatment of Ps. aeruginosa yielded a mutant deficient in taurine transaminase and incapable of growing on taurine indicating that the enzyme is of physiological significance in this organism.
