摘要：

Two times an enzyme: Trypsin was first used as a protease to catalyze the digestion of proteins and then as a ligase to catalyze the linking of isotopically labeled amino acids to the Ntermini of tryptic peptides for quantitative proteomics. Reliable and accurate quantification of proteins was demonstrated for model proteins as well as proteome samples. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
