HIGH FIDELITY THERMOSTABLE LIGASE AND USES THEREOF

摘要

The present invention is directed to a thermostable ligase having substantially higher fidelity than either T4 ligase or Thermus thermophilus ligase. The DNA molecule encoding this enzyme as well as expression systems and host cells containing it are also disclosed. The thermostable ligase of the present invention is useful in carrying out a ligase detection reaction process and a ligase chain reaction process.
