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

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
Complex formation of guanidinated bovine trypsin inhibitor (Kunitz) with trypsin, chymotrypsin and trypsinogen as studied by the spin-label technique.
Lysine residue 122 of the major protein of HBsAg/adw has been shown previously to be involved in the d subtype determinant. We demonstrate here that the corresponding residue of the HBsAg/ayw, arginine 122, does not play such a critical role
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
