Templated DNA ligation reactions are useful in a variety of contexts and have drawn much attention recently. Herein we describe two different DNA-templated ligation systems based on thiols and thiol-mediated chemistry. One system follows the principle of native chemical ligation reaction, and the other utilizes a thiol-disulfide exchange reaction.
