The ISNCY insertion sequence family, as defined by ISFinder, encodes several apparently unrelated families of transposases. Members of this family resemble the transposases of ISNCY family elements such as ISRm17 from Sinorhizobium meliloti, ISMav9 from Mycobacterium avium, and ISNfl1 from Nostoc commune.
