CABI Book Chapter Info
Cover for Glutamate decarboxylase in bacteria.

γ-Aminobutyrate (GABA) is a non-proteinaceous amino acid which plays different roles in the living systems. GABA is biochemically produced by the irreversible α-decarboxylation of L-glutamate catalysed by glutamate decarboxylase (Gad), a widespread enzyme distributed among eukaryotes and...

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 Inter-organ fluxes of amino acids.

Plasma amino acid pools are regulated by production and disposal. Whereas essential amino acids are dependent on protein breakdown for their plasma flux, non-essential amino acids are produced de novo within the body. In many instances these production processes are encased in metabolic cycles,...

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 Lysine biosynthesis in microorganisms.

Lysine is an essential amino acid that is synthesized in plants and microorganisms via two metabolic routes which evolved independently. Fungi and some archaeal species employ the intermediate α-aminoadipate to anabolize lysine. Bacteria and photosynthetic cohorts, in contrast, employ the...

Cover for Arginase and microbial pathogenesis in the lungs.

Strict regulation of pulmonary capillary barrier integrity is crucial for preventing capillary leak and ensuring optimal gaseous exchange at the alveolar-capillary interface. Bacterial infection of the lungs, as can be seen during severe pneumonia, can dramatically impair lung barrier function and...

Cover for Ornithine and lysine decarboxylation in bacteria.

The ornithine and lysine decarboxylation systems are involved in the production of putrescine and cadaverine in a number of enterobacteria, lactic acid bacteria and other Gram-positive and Gram-negative bacteria. Typically, they are composed of a specific amino acid decarboxylase and a membrane...

Cover for Hydroxyproline metabolism in microorganisms.

L-Hydroxyproline (L-Hyp) has been detected in certain proteins, particularly collagen, as well as in some peptide antibiotics. In mammalian systems, the L-proline residue in procollagen is post-translationally hydroxylated to trans-4-hydroxy-L-proline (T4LHyp) or trans-3-hydroxyl-proline (T3 LHyp). ...

Cover for Insights on <i xmlns="http://www.w3.org/1999/xhtml">O</i>-acetylserine sulfhydrylase structure, function and biopharmaceutical applications.

Bacteria assimilate sulfur via a reductive pathway that leads to L-cysteine synthesis. The last step is catalysed by the pyridoxal 5′-phosphate dependent enzyme O-acetylserine sulfhydrylase (OASS). Two isoenzymes, OASS-A and OASS-B, have been identified that share similar binding sites, although...
