Multiple alignment of Buchnera repA sequences.
(A) Schematic representation of protein multiple
alignment. Arrows in the region between amino acids 98 and 172 indicate
location of segments that are identical among the repA1
and repA2 genes of plasmids pleu-BTs (upper arrows,
positions 98–117 and 128–163) and pBGu1 (lower arrow, position
128–172). Gray blocks in the C-terminal domain indicate location and
length of two deletions present in all repA2 genes.
(B) Pairwise nucleotide sequence alignments of region of
repA from plasmids pleu-BTs, pBGu1, and pleu-BDn,
corresponding to amino acid positions 90–180, illustrating segments of
complete identity in Ts-repAs (positions 292–350 and
383–489) and Gu-repAs (position 382–516).
