Fig. 1. vap regions 1, 2 and 3 of D. nodosus strain A198 compared with the intC element in D. nodosus strain C305. The numbers show the distance in kb from the left-most NruI site in strains A198 or C305. Restriction sites shown are BamHI (B), EcoRI (E), HindIII (H), KpnI (K), NruI (N), SacI (S) and XhoI (X). The major potential genes are indicated by open arrows. The tRNA-ser genes are shown by black triangles. Repeated sequences (Cheetham et al., 1995 ) are indicated as follows: 19 bp att sites (small open boxes), 103 bp repeats, or partial copies thereof (small shaded boxes), 102 bp repeats, or partial copies (small black boxes) and the putative origin of replication (large shaded box). The large open boxes show regions which are not found in strain C305.
