The concentration of proline was found to be similar in the epidermis, the vascular bundles and mesophyll parenchyma protoplasts of barley seedlings. In stressed leaves, proline was accumulated mainly in the vascular bundles ...

A multicomponent 1,3-dipolar cycloaddition between heterocyclic aldehydes, amino esters and dipolarophiles is efficiently promoted by silver acetate as catalyst, and depending on the nature of the heterocycle and its ...

The proline peptide isomerization model of protein folding predicts that the fraction of denatured polypeptide chains which rapidly fold should be quantitatively related to the numbers of cis and trans proline residues in ...

Water deficit increased susceptibility of barley to the aphid Schizaphis graminum. Proline and glycine-betaine accumulated in the stressed plants. These compounds were incorporated into artificial diets to test their effects ...

Leukotriene A(4) hydrolase is a soluble enzyme with epoxide hydrolase and aminopeptidase activities catalysing the conversion of leukotriene A(4) to leukotriene B-4 and the hydrolysis of the peptide proline-glycine-proline. ...

The ortho-aminobenzoic acid (Abz) group is widely employed as a fluorescent marker for peptides used as substrates for the study of proteolytic enzyme activity. in fact, a direct correlation has been observed between ...

The chronic daily administration of isoproterenol provokes in mouse parotid glands the induction and progressive accumulation of a family of secretory polypeptides named polypeptides C, D, E, F, and G (polypeptides C- G). ...

Different infestation levels with the greenbug (Schizaphis graminum Rondani) were correlated with physiological parameters and several metabolite concentrations in young barley plants (Hordeum vulgare cv Aramir). Leaf water ...
