            This sequence is the first 92 bp of that referred to as SRRHGKH-a
            in [J. Protozool. 34, 429-434 (1987)].  It also could be referred
            to as mic-SR-a by the
            conventions in [J. Protozool. 34, 429-434 (1987)]
            
            The 81-MAC chromosome family is created by alternative processing
            of the micronuclear DNA.  The 81-MAC family consists of three sizes
            of macronuclear chromosomes: 4.9 kb (MACI), 2.9 kb (MACII), and 1.6
            kb (MACIII).  Alternative processing results from alternative
            choice of chromosome break/telomere-addition sites.  The 1.6 kb
            region in common between the three chromosomes bears a transcribed
            open reading frame, the conceptual translation product of which is
            homologous to solute carrier proteins from plants and metazoans.
            There are three distinct micronuclear loci (sequence versions),vA,
            vB, and vC.  Alternative processing of each micronuclear version
            independently gives rise to a I+II+III family of macronuclear
            chromosomes.  The open reading frame is conserved in all three
            versions.  Little is known about the structure of vB micronuclear
            DNA (no clones), but vA and vC micronuclear DNAs bear
            micronucleus-limited sequences called internal eliminated sequences
            (IESs).  vA and vC have small IESs in common, but in addition, vC
            bears two large transposons, TBE1-1 and -2, which also are IESs.
            IESs are precisely excised, leaving one short flanking direct
            repeat in macronuclear DNA.
            
            Only one copy of the tandem repeat (positions 56-69) is found in vB
            and vC.

COMMENT
            [Cell 43, 759-768 (1985)]  sites; telomere-bearing element
            description.
            
            Draft entry and computer-readable sequence for [J. Protozool. 34,
            429-434 (1987)] kindly provided
            by G.Herrick, 12-DEC-1986.
            
            Bases 1-237 are from region mic-rK-c; 194-372 and 443-591 from
            GKH-c; and 232-591 from mic-KH-c as referred to in [J. Protozool.
            34, 429-434 (1987)].
            
            This sequence would be named 'mic-rKH-c' by the conventions in [J.
            Protozool. 34, 429-434 (1987)].
            
            The 81-MAC chromosome family is created by alternative processing
            of the micronuclear DNA.  The 81-MAC family consists of three sizes
            of macronuclear chromosomes: 4.9 kb (MACI), 2.9 kb (MACII), and 1.6
            kb (MACIII).  Alternative processing results from alternative
            choice of chromosome break/telomere-addition sites.  The 1.6 kb
            region in common between the three chromosomes bears a transcribed
            open reading frame, the conceptual translation product of which is
            homologous to solute carrier proteins from plants and metazoans.
            There are three distinct micronuclear loci (sequence versions),vA,
            vB, and vC.  Alternative processing of each micronuclear version
            independently gives rise to a I+II+III family of macronuclear
            chromosomes.  The open reading frame is conserved in all three
            versions.  Little is known about the structure of vB micronuclear
            DNA (no clones), but vA and vC micronuclear DNAs bear
            micronucleus-limited sequences called internal eliminated sequences
            (IESs).  vA and vC have small IESs in common, but in addition, vC
            bears two large transposons, TBE1-1 and -2, which also are IESs.
            IESs are precisely excised, leaving one short flanking direct
            repeat in macronuclear DNA.
            
            When the short IES is excised the 5' imperfectly duplicated
            sequence 'atta' remains in the macronuclear DNA.  Similarly, when
            TBE1-2 is excised one flanking 'aat' remains in macronuclear DNA.
            The sequence of the homologous macronuclear DNA can be found in a
            separate entry, accession number M25391.
