A powerful approach to relative quantification by mass spectrometry is to employ labeling reagents that target specific functional groups in molecules of interest. A quantitative comparison of two or more samples may be readily accomplished by using a chemically identical

Two variants of chloramphenicol acetyltransferase which are specified by genes on plasmids found in Gram-negative bacteria were subjected to amidination with methyl acetimidate to determine the relative reactivity of surface lysine residues and to search for unreactive or "buried" amino

N epsilon-Acetimidoglucagon to be used for semisynthesis was prepared by reacting glucagon with methyl acetimidate hydrochloride at pH 10.2, favoring acetimidation of the sole epsilon-amino group. N epsilon-Acetimidoglucagon was isolated from the crude acetimidoglucagon mixture by anion-exchange chromatography at pH

To study the structural importance of the NH2-terminal Ala1 residue of pancreatic phospholipase A2, several mutants were prepared by a stepwise semisynthetic approach. 13C NMR spectroscopy of 90%-enriched [[3-13C]Ala1] phospholipases A2 shows the pK values of the alpha-NH3+ groups of

Incubation of purified cardiac sarcolemmal vesicles (SL) in the presence of S-adenosyl-L-methionine, a methyl donor for the enzymatic N-methylation of phosphatidylethanolamine (PE), increased the Ca2+-stimulated ATPase and ATP-dependent Ca2+ accumulation activities. Quantitative analysis of the methylated phospholipids revealed that maximal
