a
Values are the percentages of each base among 52 MSEs found upstream of genes that were observed to be bound by Sum1 protein (17) (see Materials and Methods for details).
b
The consensus (shown at top with position numbers) was chosen using the preferences noted in this table (see Materials and Methods for details). Bases that exhibit statistically significant differences from the control set of sequences are shown in bold and underlined. W: A or T; N: A, G, C, or T; K: G or T; D: A, G, or T. Statistical comparison of these base preferences to the control set (Table 6) yielded the following chi square test P values: Position 3, 0.031; 4, 0.0061; 5, 1.8 × 10−4; 6, 1.7 × 10−9; 7, 0.018; 9, 7.5 × 10−5; 14, 0.044; and 15, 0.0012.
