FIG. 2.

Characteristics of the MHY1 gene and its encoded protein, Mhy1p. (A) Nucleotide sequence of the MHY1 gene and deduced amino acid sequence of Mhy1p. A putative TATA box is underlined. Putative transcription termination signals are doubly underlined. The transcriptional start site of the MHY1 gene is indicated by the arrow. SPRE, putative stationary-phase response elements. The segment of Mhy1p containing the two C₂H₂-type zinc finger motifs is boxed. (B) Amino acid sequence alignment of the two zinc finger domains of Mhy1p and of S. cerevisiae Msn2p, Msn4p, and Yer130cp. Identical (asterisks) and conserved (dots) amino acids are indicated. Cys and His residues capable of binding zinc ions are boxed. The STRE sequence 5′-AGGGG and the amino acids that bind it are indicated.
