FIG. 1

(a) Molecular organization of the abiG locus on a 5.8-kb segment of pCI758 (adapted from reference 23). The two open reading frames of abiG and orfX (of unknown function) are indicated by horizontal arrows. Inline graphicindicates a 309-bp direct repeat with 5 mismatches. Inline graphicand Inline graphicrepresent putative promoter sequences and terminator structures, respectively. Gi-GSP and Gii-GSP are PCR-generated probes specific for abiGi and abiGii, respectively. Lowercase letters a through d represent primers. (b) A 3.5-kb insert of pCI735. (c) The mapped promoter and transcriptional start site (+1) upstream of abiGi.
