CABI Book Chapter Info
Cover for Flavour formation from leucine by lactic acid bacteria (LAB).

Leucine belongs to the branched-chain amino acids, which in lactic acid bacteria (LAB) can be intracellularly converted into different aromatic compounds through various enzymes and metabolic routes. The aldehyde 3-methylbutanal, the alcohol 3-methylbutanol and the carboxylic acid 3-methylbutyric...

Cover for Microbial degradation of phenolic amino acids.

Ferroglobus placidus is a hyperthermophilic archaeon from the family Archaeoglobaceae that is able to completely oxidize the phenolic amino acids tyrosine and phenylalanine to CO2 under strict anaerobic conditions with ferric iron acting as its sole electron acceptor. The compounds phenylacetate...

Cover for The biosynthesis of tryptophan.

In microorganisms and plants, L-tryptophan is biosynthesized from chorismate by a series of seven enzyme-catalysed reactions. The enzymes pathway has attracted attention both as a source of therapeutic targets and because of its evolutionary details. This chapter describes the enzymatic steps...

Cover for Tryptophan biosynthesis in bacteria: drug targets and immunology.

Tryptophan is an energetically expensive amino acid to manufacture, which makes it an important point of contest between pathogenic bacteria and their hosts. Further, the mammalian innate immune response depletes the amount of tryptophan available for uptake by bacteria. This is an effective...

Cover for The kynurenine pathway of tryptophan metabolism in microorganisms.

In this chapter, the kynurenine pathway in bacteria, archaea, unicellular fungi and protists is reviewed. The kynurenine pathway is the major catabolic pathway for L-tryptophan metabolism in prokaryotes and eukaryotes. There are two different kynurenine pathways, sometimes called 'inducible' and...

Cover for Histidine degradation in bacteria.

The ability to degrade histidine is both broadly distributed and highly conserved within the bacterial kingdom. In many cases, the complete catabolism of histidine to glutamate, ammonia and either formate or formamide allows the use of histidine as a carbon source, nitrogen source, or both. In some ...

Cover for The histidine phosphatase superfamily in pathogenic bacteria.

The histidine phosphatase superfamily is a large group of proteins whose functions are based on the phosphorylation of a histidine residue during catalysis. Apart from a few exceptions, they share a signature arginine, histidine, glycine (RHG) near the N-terminal. They are found in both eukaryotes...

Cover for Functions and metabolism of D-amino acids in microorganisms.

All naturally occurring amino acids, except glycine, have two chiral forms, L (laevorotatory) and D (dextrorotatory). L-Amino acids occur predominantly in nature, but certain D-amino acids have also been found in various organisms. Microorganisms are a major source of D-amino acids in nature, and...

Cover for Rhizobial amino acid metabolism: polyamine biosynthesis and functions.

Polyamines are ubiquitous polycationic molecules that have vital roles in many aspects of prokaryotic and eukaryotic cellular physiology. Most of the commonly occurring polyamines are synthesized from the basic L-amino acids arginine, ornithine and lysine. Polyamines produced by rhizobia, the...

Cover for Working together: amino acid biosynthesis in endosymbiont-harbouring Trypanosomatidae.

Endosymbiosis, i.e. a cell living inside another organism's cell, is a widespread phenomenon with important evolutionary and metabolic aspects. Among the many taxa presenting endosymbiosis are the genera Strigomonas, Kentomonas and Angomonas from the Trypanosomatidae family (phylum Euglenozoa)....
