Factor Xa cleavage of fusion proteins. Elimination of non-specific cleavage by reversible acylation.

FEBS letters - 9 Apr 1990

Wearne S J

Abstract excerpt

A method is described for the elimination of non-specific cleavage of fusion proteins by factor Xa. Putative non-specific cleavage sites C-terminal to lysyl residues are blocked by reversible acylation by 3,4,5,6-tetrahydrophthalic anhydride prior to cleavage. After cleavage, the acyl groups are removed quantitatively by exposure to slightly acidic conditions. This method employs no harsh reagents or conditions,...
