Fig. 5. Sequences of footprinted regions observed in Fig. 4. (A) Footprinting in the termination region of tRNA_leu. The conserved binding sequence of mTERF (Valverde et al., 1994b) is boxed. (B) The sequence in the control region located approximately 75 nt 5' of the tRNA_met gene in an area thought to contain the L-strand promoter (Carrodeguas and Vallejo, 1997). The L strand was footprinted in both cases. Primers used were LEU 1 for A and LSP 1 for B (see Table 1 for primers). Genomic positions are indicated. Relative to naked DNA, overmethylated residues are filled squares and undermethylated residues are unfilled squares.
