Abstract: A method for synthesising a given peptide or its derivative which contains a proline residue or a proline derivative, at proximity to, or at, the C-terminal end of said peptide is provided. The method comprises a) synthesising on a first resin a Cterminal portion of said peptide, o r its derivative, comprising at least three successive amino acid residues or their derivatives, by successive coupling of selected amino acids, small peptides or their derivatives, b) cleaving the C-terminal portion from said first resin; c) reattaching said C-terminal portion to a second resin which is generally suitable for the synthesis of peptides but is unsuitable for the formation of peptides having a proline residue positioned atthe C-terminal end of said peptide; and d)coupling selected amino acids, small peptides or derivatives to the C-terminal portion.

Abstract: A method of ligating two or more molecules, for example, peptides to peptides or peptides to labels is provided. The method may comprise the steps: a) providing a first oligopeptide having a reactive moiety, which is a hydrazine moiety, a hydrazide moiety or an amino-óxy moiety b) providing a second oligopeptide having an activated ester moiety, c)allowing the reactive moiety of the first oligopeptide to react with the activated ester moiety of the second oligopeptide to form an oligopeptide product, in which the first and second oligopeptides are linked via a linking moiety having Formula I, II or III. The second oligopeptide may preferably be generated by thiol reagent induced cleavage of an intein fusion protein. The invention further provides labelling and ligation methods in which protein hydrazides are ligated by reaction of the hydrazide moiety with an aldehyde functionality or a ketone functionality.
Abstract translation: 提供了将两个或多个分子例如肽与肽或肽连接至标记的方法。 该方法可以包括以下步骤:a)提供具有反应性部分的第一寡肽,其为肼部分,酰肼部分或氨基-o-部分b)提供具有活化酯部分的第二寡肽,c)允许反应性 第一寡肽的部分与第二寡肽的活化酯部分反应以形成寡肽产物,其中第一和第二寡肽通过具有式I,II或III的连接部分连接。 第二寡肽可以优选地由硫醇试剂诱导的内蛋白融合蛋白的切割产生。 本发明进一步提供了标记和连接方法,其中蛋白质酰肼通过酰肼部分与醛官能团或酮官能团的反应连接。

Abstract: Disclosed is a tag for purification of peptides, The tag structure facilitates the easy cleavage of a bond formed between the tag molecule and a peptide to which it is bound under conditions which minimise, indeed preferably prevent, damage to the peptide. The tag molecules of the invention may be used to separate and/or purify a peptide from a mixture of peptides and/or other components.
