Proteins which show homologies to the B-block binding subunits of human and S. pombe , and the Arabidopsis protein GI 25402830. A. The result of a PSI-BLAST search using the human subunit (GI 4753161) as a query. B. The result of a PSI-BLAST search using the S. pombe subunit (GI 19112919) as a query. C. The result of a PSI-BLAST search using the Arabidopsis protein (GI 25402830) as a query. In A-C, only the proteins that had bit scores more than 200 are shown. Bold horizontal lines (black, dark gray, and pale gray lines) are the regions that appeared as convergent iterative alignments. The numbers above the lines are the amino acid positions in the query sequence, and those beneath the lines are the amino acid positions in the hit sequences. When more than two regions were hit in the same sequence, the highest bit score and E-value are shown. Black lines are the alignments that had the best bit scores and E-values. Gray-colored alignments had the worse scores. Dark gray lines represent the alignments with the bit scores more than 200, and the scores of the pale grey alignments are lower than 200. The proteins that had similarities only in short regions (smaller than about 300 amino acids) were omitted, even if the bit scores were more than 200. The case of the Ustilago sequence is exceptional. This result was from the PSI-BLAST which was limited a search of the fungi database. The bold horizontal lines are the regions that appeared as convergent iterative alignments, and below them E-values are shown.
