Amino acid decarboxylases of lactic acid bacteria.
Many strains of a wide variety of bacterial species have been studied for their amino acid decarboxylase activity (Gale, 1946). However, to our knowledge the lactobacilli have not been examined. It has been shown in our laboratory that oral lactobacilli may be classified into three types according to their ability to attack certain carbohydrates, intensity of acid production from glucose, and b...
متن کاملCharacterization of neutral amino acid transport in a marine pseudomonad.
The transport of neutral amino acids in marine pseudomonad B-16 (ATCC 19855) has been investigated. From patterns of competitive inhibition, mutant analysis, and kinetic data, two active transport systems with overlapping substrate specificities were distinguished and characterized. One system (DAG) served glycine, D-alanine, D-serine, and alpha-aminoisobutyric acid (AIB) and, to a lesser exten...
متن کاملA Method for the Determination of Some Amino Acid Decarboxylases*
Mammalian organs are known to decarboxylate a number of n-amino acids. Of the mammalian decarboxylases, 3,4-dihydroxyphenylalanine decarboxylase is probably the most studied. Blaschko (1) reported values for DOPAl decarboxylase in .liver and kidney of several animal species. The enzyme was shown to be deactivated by dialysis and its activity restored by the addition of pyridoxal phosphate (2, 3...

متن کاملSensing and Adaptation to Low pH Mediated by Inducible Amino Acid Decarboxylases in Salmonella
During the course of infection, Salmonella enterica serovar Typhimurium must successively survive the harsh acid stress of the stomach and multiply into a mild acidic compartment within macrophages. Inducible amino acid decarboxylases are known to promote adaptation to acidic environments. Three low pH inducible amino acid decarboxylases were annotated in the genome of S. Typhimurium, AdiA, Cad...
