FIG. 1.
Genetic and transcriptional organization of the Tn5276-located sucrose gene cluster of L. lactis NZ9800. The genes (open arrows) are shown with their products and mapped promoters (arrowheads) as well as the mapped transcripts (arrows). Cloned chromosomal DNA fragments relevant to this study are illustrated below the arrows, as are the names of the derived plasmids on which they are carried. The putative terminator downstream of the sacK gene is indicated (T1). Relevant restriction sites are shown as follows: B, BamHI; K, KpnI; M, MunI; P, PstI; and X, XbaI.
