The selectivity of amino acid and peptide amidination with O-methylisourea.

H Wojciechowska et al.

Acta biochimica Polonica, 29(3-4), 197-204 (1982-01-01)

Selectivity of amidination using ornithine as model amino acid was investigated in detail. The results obtained were taken advantage of for studying the reactions with other polyfunctional amino acids: beta-tyrosine, isoserine, 2,3-diaminopropionic acid, 2,6-diamino-7-hydroxyazelaic acid and with the pentapeptide amide

Integrating Lys-N proteolysis and N-terminal guanidination for improved fragmentation and relative quantification of singly-charged ions.

Valerie J Carabetta et al.

Journal of the American Society for Mass Spectrometry, 21(6), 1050-1060 (2010-03-09)

The study of isolated protein complexes has greatly benefited from recent advances in mass spectrometry instrumentation and quantitative, isotope labeling techniques. The comprehensive characterization of protein complex components and quantification of their relative abundance relies heavily upon maximizing protein and

Changes in protein stability upon chemical modification of lysine residues of bovine serum albumin by different reagents.

K M Fazili et al.

Biochemistry and molecular biology international, 31(5), 807-816 (1993-12-01)

Using acetic anhydride, potassium cyanate and O-methyl isourea six chemically modified derivatives of bovine serum albumin with chemical modification on lysine side chains have been prepared. All the modified preparations were found to be homogeneous with respect to size and
