Lysine ligation
WebFig. 4 (A) Stochastic reaction with surface-exposed lysine residues results in a heterogeneous product; (B) structures of lysine-selective reagents and their products upon conjugation. A range of lysine-selective reagents have been developed ( Fig. 4B ). WebThis approach was successfully used for the synthesis of a lysine-63-linked diubiquitin conjugate by ligation of the modified ubiquitin(1-52)-Cys- donor peptide to the N-terminal Arg-54 residue of the branched Lys-63-linked acceptor peptide, ubiquitin(54-76)(2).

Websual lysine-ligated heme (heme 2) at the active site. This uncon-ventional lysine heme ligation has been previously observed only for the heme 1 binding site of the pentaheme cytochrome c nitrite reductases from Wolinella succinogenes [4] and other bacteria, but in these cases the lysine ligand is located in a CXXCK motif. WebE. coli DNA Ligase is a ligation enzyme that can be used to join DNA fragments by catalyzing the formation of phosphodiester bonds between double-stranded DNA fragments containing juxtaposed 5'-phosphate termini and 3'-hydroxyl termini in the presence of the NAD cofactor. Both E.coli DNA Ligase and T4 DNA Ligase are used in gene cloning …
