Nothing is known of the biosynthesis of tetrodotoxin, although the involvement of arginine and an isoprenoid has been postulated (191). Radiolabeled acetate, arginine, citrulline, or glucose were not incorporated into the tetrodotoxin of newts of the genus Taricha (210). [Pg.267]

In general the thiol proteases catalyze the hydrolysis of a variety of peptide, ester, and amide bonds of synthetic substrates. Employing the general formula R —NH—CHR—CO—X, cleavage of the —CO—X— bond has been demonstrated when R represents the side chain of glycine, threonine, methionine, lysine, arginine, citrulline, leucine, and tyrosine. [Pg.210]

Several standard and nonstandard amino acids act as metabolic intermediates. For example, arginine, citrulline, and ornithine (Figure 5.6) are components of the urea cycle (Chapter 15). The synthesis of urea, a molecule formed in vertebrate livers, is the principal mechanism for the disposal of nitrogenous waste. [Pg.118]

Over the past 5 years, diverse lines of evidence have converged to suggest the presence of a mammalian-type NOS in plants. Evidence for the presence of NOS activity was first described in the leguminous plant Lupinus Albus [187]. A L-arginine-dependent L-citrulline production, possibly induced by Rhizobium lipopolysaccharides, was measured in roots and nodules using the [14C]arginine/citrulline procedure. L-citrulline production was inhibited by the mammalian NOS antagonist N(G)-... [Pg.931]

No activity was detected with the a-keto acid analogs of glycine, glutamine, asparagine, phenylalanine, tyrosine, tryptophan, arginine, citrulline, and aspartate. [Pg.394]

In addition to more or less complete amino acid separations, suitable chromatographic systems for the rapid determination of selected amino acids [4-amino-butyric acid (GABA) [336], histidine and 3-methylhisti-dine [367] or a group of selected amino acids, such as those involved in the urea cycle (arginine, citrulline, ornithine, agmatine) [368], have been reported. Precolumn derivative formation with OPA/R-SH reagents is also suited to the automated establishment of peptide maps [369]. A number of authors have published methods for the sensitive determination of aminoglycoside antibiotics [365,370—373]. The method has also found application for the determination of histamine and its methylation products [374—376], catecholamines and serotonin [377—379] and polyamines [380]. [Pg.195]

Oenersl Properties of the Amino Acids.— All the natural acids are colourless crystalline solids. All, except cystine, leucine, and tyrosine, are readily soluble in water and all, except proline and hydroxyproline, are sparingly soluble in alcohol. AU are optically active, except glycine, the a-carbon of which is not asymmetric. The dextro acids are alanine, valine, iso-leucine, glutamic acid, hydroxyglutamic acid, aspartic acid, arginine, citrulline, and lysine. The others are IsBvo-rotatory. [Pg.135]

Amino acids can be obtained from purified proteins by chemical or enzymatic hydrolysis. They also can be isolated from industrial byproducts, extracted from plant or animal tissues, or synthesized by organic, enzymatic, or microbiological means. Amino acids that are produced industrially by fermentation include arginine, citrulline, glutamic acid, glutamine, histidine, isoleucine, leucine, lysine, ornithine, phenylalanine, proline, threonine, tryptophan, tyrosine, and valine. [Pg.953]

The enzymes of the urea cycle, however, are not only expressed in the liver, but also in other tissues and cell types. In fact, it is believed that the urea cycle evolved from the arginine metabolic pathway present in lower organisms (Takiguchi et al, 1989). This difference in function between urea and arginine synthesis is reflected by the different tissue localization, function and regulation of the enzymes of the urea cycle and other enzymes involved in the metabolism of the urea cycle intermediates, arginine, citrulline and ornithine. [Pg.87]
