Nucleotide sequences of the 5'-flanking regions of the multifunctional protein-1 ( MFP-1 ) and thiolase-B ( ThB ) genes respectively. Each transcription start site is numbered +1 and the sequence of Exon I are shadowed. Upstream nucleotides of this site are shown by negative numbers. The ATG codon encoding the first methionine is indicated in bold. Putative sequences for NFY and Sp1 motifs are shown.
