CC   Yeast 2 micron plasmid contains two 599 bp inverted repeats
CC   separated by a large unique (UL) and a small unique (US) region.
CC   During recombination the UL and US regions invert producing two
CC   sequence forms that differ in the orientation of one unique region
CC   relative to the other.  The A form is presented below.
CC   FLP is the only 2-micron circle-encoded protein needed for specific
CC   site recombination between the IRs of 2-micron circle.  The minimal
CC   size of the recombination site required for efficient FLP
CC   recombinase-catalyzed recombination in vitro is no more than 28 bp,
CC   which includes parts of two 13 bp inverted repeats (positions
CC   690-702 and 711-723) and all of an 8 bp spacer (703-710) [5].  The
CC   FLP recombinase cleaves the DNA at the boundaries of the spacer and
CC   becomes covalently linked to the spacer DNA [5],[9].  The
CC   efficiency of the recombination is reduced if the spacer in a
CC   recombinant site is increased or decreased by 1 bp, while the
CC   spacer in the second site is unaltered [5].  Recombination between
CC   two sites with identical 1-base pair additions or deletions is
CC   relatively unaffected, suggesting that pairing of sequences in the
CC   spacer regions is important in FLP-promoted recombination events
CC   [5].  The sequence asymmetry utilized by the recombinase to
CC   determine the orientation of the site is located uniquely within
CC   the spacer region. Another 13 bp direct repeat, is found at
CC   positions 676-688 [5].  FLP-mediated recombination involving two
CC   FLP sites that are inverted with respect to each other results in
CC   inversion of the DNA sequences between the sites [4].  If the
CC   participating recombination sites are in direct orientation, FLP
CC   promotes only the excision of the intervening DNA sequences [4].
CC   The Rep 1 and Rep proteins are involved plasmid partitioning and
CC   protein stability.
CC   A start codon in phase with the Rep1 coding region is located at
CC   positions 1966-1964.  Two CAP sites for Rep1 mRNA are located
CC   beyond the 'atg' codon (position 2008) at positions 2004 and 2005.
