FIG. 1.
(A) Map of the ftsW-psr-pbp5 locus of E. hirae. (B) ftsW-psr-pbp5 loci of the different E. hirae recombinants. The arrows indicate the orientation of transcription. The solid rectangle at the origin of psr corresponds to the 87-bp deletion present in R40 and its FS1 derivative. The spcR and kmR inserts indicate the positions of the resistance cassettes. The hybridization sites of the O8 to O13 probes used in PCR are also shown. The restriction sites are indicated as follows: E, EcoRI; H, HindIII; P, PstI; Hc, HincII; K, KpnI.
