    • A nucleotide sequence characteristic of Neisseria gonorrhoeae is disclosed. The sequence can be the basis for hybridization type, nucleic acid-based, rapid, in vitro diagnostic assays. The unique nature of the sequence makes it possible to clearly discriminate N. gonorrhoeae from other Neisseria species thus eliminating or substantially reducing the number of false positive readings. A 350 base pair N. gonorrhoeae DNA restriction fragment was cloned after subtractive hybridization to Neisseria meningitidis DNA. In further cloning experiments the sequences adjacent to the original 350 base pair fragment were determined. A portion of this sequence was shown to detect 105 of 106 N. gonorrhoeae strains and no other Neisseria species. In addition to use as detection probes, all or portions of the nucleotide sequence can be used as a ligand for the sandwich capture of N. gonorrhoeae sequences and as primers for in vitro amplification of N. gonorrhoeae sequences. The polypeptides encoded by the presently disclosed sequence, including antibodies thereto, are also disclosed as are their uses.
    • 披露了淋病奈瑟氏球菌特征的核苷酸序列。 该序列可以是杂交类型,基于核酸,快速,体外诊断测定的基础。 序列的独特性质使得可以清楚地区分淋病奈瑟氏球菌与其他奈瑟氏菌属物种,从而消除或显着减少假阳性读数的数量。 在与奈瑟氏球菌脑膜炎奈瑟菌DNA消减杂交后克隆了350碱基对淋病奈瑟氏球菌DNA限制性片段。 在进一步克隆实验中,确定与原始350碱基对片段相邻的序列。 该序列的一部分显示检测到106个淋病奈瑟氏球菌菌株中的105个,并且没有其他的奈瑟球菌属物种。 除了用作检测探针之外,核苷酸序列的全部或部分可以用作奈氏淋病奈瑟氏球菌序列的夹心捕获的配体,并且用作用于体外扩增淋病奈瑟氏球菌序列的引物。 本文公开的序列编码的多肽(包括其抗体)也被用于其用途。

    • The present invention is directed to recombinant hosts which contain and express various Type II restriction endonuclease and/or modification methylase genes. In particular, the present invention is concerned with the cloned restriction endonucleases, NgoAIII and NgoAI, which recognize and cleave within or near the double-stranded DNA sequence, 5' CCGCGG 3' and 5' PuGCGCPy 3', respectively. Also provided in this invention are cloned modification methylase genes corresponding to said restriction endonucleases. This invention is further concerned with a cloned modification methylase, M.NgoAII. One source of these enzymes is Neisseria gonorrhoeae, although other microorganisms may be used to isolate the restriction endonuclease isoschizomers and modification methylase isoschizomers of this invention.
    • 本发明涉及含有并表达各种II型限制性内切核酸酶和/或修饰甲基化酶基因的重组宿主。 特别地,本发明涉及克隆的限制性内切核酸酶NgoAIII和NgoAI,其分别在双链DNA序列内或其附近识别和切割5'CCGCGG 3'和5'PuGCGCPy 3'。 本发明还提供了与所述限制性内切核酸酶相应的克隆的修饰甲基化酶基因。 本发明还涉及克隆的修饰甲基化酶M.NgoAII。 这些酶的一个来源是淋病奈瑟氏球菌,尽管其他微生物可用于分离本发明的限制性内切核酸酶异构体和修饰甲基化酶同位异构体。
