Biosynthesis of a D-amino acid in peptide linkage by an enzyme from frog skin secretions.
d-amino acids are present in some peptides from amphibian skin. These residues are derived from the corresponding L-amino acids present in the respective precursors. From skin secretions of Bombinae, we have isolated an enzyme that catalyzes the isomerization of an L-Ile in position 2 of a model peptide to D-allo-Ile. In the course of this reaction, which proceeds without the addition of a cofa...
متن کاملHost-defense peptides isolated from the skin secretions of the Northern red-legged frog Rana aurora aurora.
Antimicrobial peptides in the skin secretions of anurans constitute a component of the innate immunity that protects the organism against invading pathogens. Four peptides with antimicrobial activity were isolated in high yield from norepinephrine-stimulated skin secretions of the Northern red-legged frog Rana aurora aurora and their primary structures determined. Ranatuerin-2AUa (GILSSFKGVAKGV...
متن کاملThe ascaphins: a family of antimicrobial peptides from the skin secretions of the most primitive extant frog, Ascaphus truei.
The tailed frog Ascaphus truei occupies a unique position in phylogeny as the most primitive extant anuran and is regarded as the sister taxon to the clade of all other living frogs. Eight structurally related peptides, termed ascaphins 1-8, were isolated from norepinephrine-stimulated skin secretions of A. truei and were shown to possess differential growth inhibitory activity against Escheric...
متن کاملThe Frog Skin Potential
For many years the isolated surviving frog skin has been among the favorite objects of electrophysiologists and students of ion transport. This interest has turned out to be rather rewarding. Not only is the frog skin preparation interesting in its own rights, but there is mounting evidence that it can serve as a model system for the study of properties found in many epithelial and glandular ti...
