Alignment of histone promoter sequences by A-GLAM. Figure 2A indicates the ranking of individual elements from each sequence, based on their E-values. The six columns in each line of the alignment represent: (1) start position (2) the sequence of the predicted motif instance (3) end position (4) strand (5) individual score and (6) the corresponding E-value. The nucleotides matching the consensus are represented in bold letters. Figure 2B shows the sequence logo for the predicted motifs within the histone promoters. (The Methods section gives a brief explanation of sequence logos.) The letters at the top of the logo closely match the consensus of the histone UAS.
