    • Methods and reagents for obtaining simplified mixtures of peptides from a sample containing a number of peptides are disclosed. The simplified sample can be easier to analyze than the original peptide sample yet it is representative of all or nearly all of the proteins present in the mixed protein sample from which the original and more complex peptide sample was derived. The methods entail the use of tagging moieties that include an amino-acid-specific reactive group (R). The tagging moieties "tag" peptides or proteins at specific amino acids (e.g., by reacting with an amino acid to form a covalent bond), ultimately allowing the isolation of peptides that contain those specific amino acids. Other methods entail the used of a reactive moiety (R p ) that comprises a reagent that selectively interacts with selected proteins, either covalently or noncovalently. For example, R p can be a natural ligand for a receptor that is to be taged or a protein that interacts with a second protein that is to be tagged. It can be an enzymatic substrate or other element of molecular recognition such as an antibody, ATP, GTP, NAD, NADP, NADH, NADPH, ubiquitin, or structural analogs thereof.
    • 公开了从含有多个肽的样品中获得肽的简化混合物的方法和试剂。 简化的样品可以比原始肽样品更容易分析,但它代表了衍生原始和更复杂的肽样品的混合蛋白样品中存在的全部或几乎全部蛋白质。 所述方法需要使用包括氨基酸特异性反应性基团(R)的标记部分。 标签部分在特定氨基酸“标记”肽或蛋白质(例如通过与氨基酸反应以形成共价键),最终允许分离含有那些特定氨基酸的肽。 其他方法需要使用包含与所选蛋白质共价或非共价选择性相互作用的试剂的反应性部分(R p)。 例如,Rp可以是待受体的受体的天然配体或与被标记的第二种蛋白质相互作用的蛋白质。 其可以是酶底物或分子识别的其它元件,例如抗体,ATP,GTP,NAD,NADP,NADH,NADPH,泛素或其结构类似物。
