CABI Book Chapter Info
Cover for L-arginine-dependent nitric oxide synthase activity.

Nitric oxide (NO) has long been recognized as a signalling molecule influencing diverse physiological processes in animals. More recently, it has emerged as an innovative topic of research in plant physiology and biochemistry. During the last decade, the involvement in a plethora of functions has...

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 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 Microbial degradation of amino acids in anoxic environments.

In the absence of terminal electron-acceptors such as sulfate, nitrate or molecular oxygen, only a few fermenting bacteria (Firmicutes) can catabolize amino acids. For every one of the 20 proteinogenic amino acids, at least one degradation pathway is known. Many pathways involve radical...

Cover for Lysine metabolism.

Lysine is an essential amino acid for growth, development and reproduction in animals and its status as the first-limiting amino acid in cereals is unequivocal. Consequently, there is continuing interest in its metabolism in higher plants. The pathway from which lysine is synthesized is now well...

Cover for Histidine.

Histidine (His) is a proteinogenic amino acid, and is thus critical for plant growth and development. The chemical properties of the imidazole side group of His allow this amino acid to participate in acid-base catalysis and in the coordination of metal ions, including zinc (Zn) and nickel (Ni)....

Cover for Amino acid synthesis under abiotic stress.

Almost all plants have to deal with climatic factors and to develop strategies to adapt their metabolism, which may have been adversely affected, in order to acclimate and survive under these unfavourable growth conditions. Mechanisms of plant stress tolerance involve some changes in gene...

Cover for Melatonin: synthesis from tryptophan and its role in higher plant.

Melatonin, a well-known neurohormone, was discovered in animal tissues in 1958. In plants, its presence was detected in 1995, and its biosynthesis, from tryptophan, seems to follow similar enzymatic steps in plant and animal cells, although with some very particular characteristics. Even though our ...

Cover for The yeast γ-aminobutyrate (GABA) shunt.

γ-Aminobutyrate acid (GABA) is a 4-carbon non-protein amino acid that is ubiquitously found in biological systems. It is both produced and degraded by a simple three-enzyme metabolic pathway consisting of glutamate decarboxylase (GAD; EC 4.1.1.15), 4-aminobutyrate aminotransferase (GABAT; EC...
