A ninhydrin reaction differentiating N-terminal glycine peptides from other peptides.
The products of the reaction of ninhydrin with a-amino acids are, in general, the corresponding aldehyde of one less carbon atom than the original compound, COZ, and, at pH 5 to 7, an intensely colored compound (thought to be the anion of diketohydrindylidene-diketohydrindamine), which contains nitrogen from the amino acid. If the pH is kept at 2.5 or lower, this colored compound is not produce...
متن کاملPuzzling Peptides from a Phage Display Library
The commercial availability of random peptide libraries displayed on the M13 phage is increasing their use forstudies on epitope identification, enzyme inhibitors, receptor ligands, etc. In this study two experimentswhere planned for selection of peptides. First with sheep antibodies, the positive selector was IgG, preparedon Protein G column from a pool of 11 sheeps immunized...
متن کاملAntimicrobial Peptides Derived from Milk: A Review
Milk proteins provide a natural source of bioactive peptides with potential health benefits and applications in the food industry. The release of these peptides from milk proteins is achieved either by hydrolysis using digestive proteases or by lactic acid bacteria fermentation. Peptides, particularly those derived from milk proteins, can exert a wide range of nutritional, functional and biolog...
متن کاملN-terminal POMC peptides and adrenal growth
The peptide hormones contained within the sequence of proopiomelanocortin (POMC) have diverse roles ranging from pigmentation to regulation of adrenal function to control of our appetite. It is generally acknowledged to be the archetypal hormone precursor, and as its biology has been unravelled, so too have many of the basic principles of hormone biosynthesis and processing. This short review f...
متن کاملN-Terminal acetyl-peptides from two calf thymus histones.
1. The same N-terminal peptide was isolated from two major calf thymus histone fractions, F2al and F2a2. 2. The structure of the peptides is N-acetylseryl-glycyl-arginine, and the yields account for most of the N-acetyl groups previously found in these histones. 3. Some other peptides not giving a ninhydrin reaction were also investigated.
