  The invention includes a selective method of modifying the N-terminus of a protein using an aminoacyl tRNA transferase. In certain embodiments, the method comprises contacting a solution of the protein or peptide with a transferase and a derivative of a molecule, whereby the N-terminus of the protein or peptide is derivatized with the molecule.

  本发明涉及使用氨酰tRNA转移酶选择性地改变蛋白质的N-末端的方法。在某些实施例中，该方法包括将蛋白质或肽的溶液与转移酶和分子的衍生物接触，从而使蛋白质或肽的N-末端与该分子发生衍生化反应。

  A selective method of modifying the N-terminus a protein using an aminoacyl tRNA transferase is provided. The method comprises reacting the protein with the aminoacyl adenosyl derivative, recognizable by AaT t-RNA transferase derived from E.Coli and similar bacterial systems. The method further includes production of protein fusion constructs by incorporation of an additional cysteine in the N -terminus and reacting this cysteine with a thioether placed on the C-terminus of a reaction partner protein, producing a fused construct. Selenocysteine can be included in the fused construct and further reduced producing alanine residue in the desired positions. An essential feature of the method is that the aminoacyl adenosine derivatives are pre-made and do not require a synthetase enzyme, allowing a great diversity of the N-terminus modifiers to be pre-made synthetically. The method is implemented as a kit.
