Metabolism of basic amino acids in Pseudomonas putida. Properties of the inducible lysine transport system.
Pseudomonas putida P2 (ATCC 25571) grown on r,-lysine or DL-pipecolic acid is induced for a high velocity lysine transport system. Double reciprocal plots of L-lysine transport in induced cells are linear. K, and V,,, values are 7.3 X 10V6 M and 130 nmoles per mm per mg for lysinegrown cells and 9.3 X 10e6 M and 42 mnoles per min per mg for cells grown on pipecolate. Lysine transport is optimal...
متن کاملMetabolism of basic amino acids in Pseudomonas putida. Intermediates in L-arginine catabolism.
y-Guanidinobutyrate amidinohydrolase, the third enzyme of L-arginine catabolism in Pseudomonas putida, has been purified 6%fold from extracts of cultures grown on L-arginine. Synthesis of the amidinohydrolase is induced by growth on L-arginine or y-guanidinobutyrate, but not by growth on y-aminobutyrate or on urea plus DL-malate. Hydrolysis of y-guanidinobutyrate to y-aminobutyrate and urea pro...
متن کاملAmino acid racemization in Pseudomonas putida KT2440.
D-Amino acids have been shown to play an increasingly diverse role in bacterial physiology, yet much remains to be learned about their synthesis and catabolism. Here we used the model soil- and rhizosphere-dwelling organism Pseudomonas putida KT2440 to elaborate on the genomics and enzymology of d-amino acid metabolism. P. putida KT2440 catabolized the d-stereoisomers of lysine, phenylalanine, ...
متن کاملThe AauR-AauS two-component system regulates uptake and metabolism of acidic amino acids in Pseudomonas putida.
Pseudomonas putida KT2440 metabolizes a wide range of carbon and nitrogen sources, including many amino acids. In this study, a sigma54-dependent two-component system that controls the uptake and metabolism of acidic amino acids was identified. The system (designated aau, for acidic amino acid utilization) involves a sensor histidine kinase, AauS, encoded by PP1067, and a response regulator, Aa...
متن کاملAromatic acids are chemoattractants for Pseudomonas putida.
A quantitative capillary assay was used to show that aromatic acids, compounds that are chemorepellents for Escherichia coli and Salmonella sp., are chemoattractants for Pseudomonas putida PRS2000. The most effective attractants were benzoate; p-hydroxybenzoate; the methylbenzoates; m-, p-, and o-toluate; salicylate; DL-mandelate; beta-phenylpyruvate; and benzoylformate. The chemotactic respons...
