Figure 5

Alignment of 5S genic regions and flanking sequences. Conserved regulatory motifs essential for the polymerase III transcription [51] are highlighted. The insertions with complete and incomplete 5S copies are separated by a horizontal line. Note the highly conserved genic regions are well separated from the highly diverged 5' and 3' sequence ends. The 3' flanking sequences are only partially aligned because of the divergence. The numbers after the species name in titles indicate clones. TATA - TATA box; TSS - transcription start site; IE - internal regulatory element; Termin. - transcription terminator. The bottom strands (with respect to the 26S gene transcription) are shown except for Madia sativa. Underlined solid line - a motif resembling reverse transcriptase primer binding site (methionine tRNA). Underlined dashed line - a motif resembling a polyadenylation site.
