FIG. 2.

Structure of the type 2 capsule locus in S. pneumoniae D39. The 21,709-bp PCR fragment used as a template for sequencing was obtained by using primers FI3 and FI4, designed on dexB and aliA, respectively. FI3, 5′-TCT TAG TTC CAT GGG ATG CTT TCT GTG TG-3′, nucleotides 657 to 685 of dexB (GenBank accession no. Z47210); FI4, 5′-CGC TGA ACT TTT GTA GTT GCT GTC TGG TCA AC-3′, complementary to nucleotides 1301 to 1270 of aliA (plpA) (GenBank accession no. L20556). Sequenced DNA is represented by the rectangle. cps genes are indicated only by their letters, and the ORFs and their direction of transcription are represented by arrows. Putative promoters (P) and transcription terminators (T) are indicated. Scale is in kilobases.
