FIG. 1.
Restriction map of the region of cosmid clone 13-6-4 that contains the tutE tutFDGH genes. The five identified open reading frames are indicated with thick arrows. Thin arrows above the map indicate the major transcriptional start sites identified. T, potential terminator site. The probes used for Northern analysis are also indicated below the map with thick lines. Potential transcripts (from the starts to the terminators) are shown below the probes with thin lines. Restriction site abbreviations: B, BamHI; C, ClaI; N, NcoI; P, PstI; R, EcoRI; Sa, SacII; Sc, SacI. Sites blocked by methylation are omitted.
