  • Title: A family of small repeated elements with some transposon-like properties in the genome of Neisseria gonorrhoeae.

    Abstract:
    A physical technique known as two-dimensional S1 nuclease heteroduplex mapping has been applied to genomic DNA from the Gram-negative coccus Neisseria gonorrhoeae. This has resulted in the detection of two novel types of repetitive sequences. The first type is a repetitive sequence family of 152 base pairs (bp), whose ends are composed of inverted repeats of 26 bp. There are approximately 20 copies of this sequence, in both N. gonorrhoeae and Neisseria meningitidis (Correia, F., Inouye, S., and Inouye, M. (1986) J. Bacteriol. 167, 1009-1011). The second type of sequence is a 1443-bp duplication in the N. gonorrhoeae genome. The two classes of sequence are linked positionally. Each copy of the long duplicated sequence is adjacent to a member of the 152-bp repetitive sequence. In one instance two copies of the 152-bp repetitive sequence are separated by a 436-bp central region and are in an inverted orientation with respect to one another, resembling a compound transposable element.
