    摘要: The present invention relates to a gene coding for a thermostable DNA ligase from Aquifex pyrophilus, a hyperthermophilic Bacterium, a protein having an amino acid sequence expressed therefrom and a probe used for detecting said ligase DNA. More particularly, the present invention is directed to a gene having a base sequence of SEQ. ID. NO: 3 and a thermostable DNA ligase having an amino acid sequence expressed therefrom (SEQ. ID. NO: 4). Since Aquifex pyrophilus DNA ligase of the present invention has 75% of the ligation activity after heating at 95 ° C. for 1 hour, the ligase has higher stability than DNA ligases from the preexisting bacteria under high temperature and thus it can be advantageously used in genetic diseases assay of medical field, etc.
