CABI Book Chapter Info
Cover for Structural and functional properties of glutamate dehydrogenases.

Glutamate dehydrogenases are homooligomeric enzymes that catalyse the reversible oxidative deamination of glutamate to 2-oxoglutarate, thereby linking nitrogen metabolism and the tricarboxylic acid cycle. Four different classes of the enzyme are known in microbes that differ in size and cofactor...

Cover for The role of nitric oxide signalling in yeast stress response and cell death.

Nitric oxide (NO) is a small gaseous molecule and free radical with important and distinct roles in diverse physiological functions in biological systems. The relevance of NO as a signalling molecule is well known, particularly in neurons as a neurotransmitter, in blood vessels as a regulator of...

Cover for Cellular responses to serine in yeast.

The serine-glycine interconversion has been the subject of considerable research over several decades and it involves series of reactions of relevance to bacteria and fungi as well as higher organisms. Much has been published on the role of cofactors and one-carbon units in this reversible...

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 ...

Candida albicans biofilms are multicellular communities formed by individual yeast cells which are extremely resistant to a wide spectrum of antifungal drugs. Based on studies carried out in vitro, C. albicans biofilm formation can be partitioned into four basic stages: the adherence stage; the...

Cover for Alanine aminotransferase: amino acid metabolism in higher plants.

Alanine aminotransferase (AlaAT, EC 2.6.1.2) catalyses the reversible transfer of an amino group from alanine (Ala) to 2-oxoglutarate to form pyruvate and glutamate. AlaAT is a pyridoxal phosphate-dependent enzyme that serves as the main route of alanine biosynthesis and degradation. This chapter...

Cover for The central role of glutamate and aspartate in the post-translational control of respiration and nitrogen assimilation in plant cells.

The assimilation of inorganic N, in the form of NH4+, into glutamine and glutamate via glutamine synthetase (GS) and glutamine oxoglutarate aminotransferase (GOGAT) is a pivotal metabolic process in plants. This is because glutamate and glutamine are the primary amino donors for the biosynthesis of ...

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...

Cover for Aminotransferases.

The aminotransferases are PLP-dependent proteins which catalyse the transfer of an amino group from the donor amino acid to α-ketoglutarate, forming glutamate and the respective keto acids. Several key aminotransferase proteins have been identified as playing central roles in whole-body nitrogen...

Cover for An outline of pathways in amino acid metabolism.

The pathways in this chapter highlight the roles of several amino acids in the metabolic processes in animals. Arginine is a key intermediate in the urea cycle, enabling mammals to dispose of waste nitrogen. Together with glycine, arginine also contributes to the formation of creatine. In poultry,...
