Metabolism of tryptophan by Pseudomonas aureofaciens. 3. Production of substituted pyrrolnitrins from tryptophan analogues.
Exogenous tryptophan is metabolized by Pseudomonas aureofaciens to yield pyrrolnitrin [3-chloro-4-(2'-nitro-3'-chlorophenyl)-pyrrole], an antifungal agent. The ability of this culture to metabolize tryptophan analogues in a similar manner was investigated by addition of the appropriate compound to the fermentation. Tryptophan precursors and metabolites or nonphenyl-substituted tryptophans had l...

متن کاملTryptophan inhibits biofilm formation by Pseudomonas aeruginosa.
Biofilm formation by Pseudomonas aeruginosa has been implicated in the pathology of chronic wounds. Both the d and l isoforms of tryptophan inhibited P. aeruginosa biofilm formation on tissue culture plates, with an equimolar ratio of d and l isoforms producing the greatest inhibitory effect. Addition of d-/l-tryptophan to existing biofilms inhibited further biofilm growth and caused partial bi...
متن کاملTryptophan Oxygenase of Pseudomonas acidovorans
Tryptophan oxygenase (L-tryptophan: oxygen oxidoreductase, EC 1.13.1.12) was purified to a state of homogeneity from substrate-induced Pseudomonas acidovorans. The sedimentation and diffusion coefficients of the homogeneous protein are SU),~, 6.26 x lo-l3 set, and DzO w, 4.78 X 10d7 cm2 set-l, and from these values a molecular weight, M,,D, of 121,000 is obtained. High and low speed equilibrium...
