Fig. 2. (A) The genomic structure of forC and the forC disruption
construct. (B) Agarose gel electrophoreses of the forC locus obtained
by genomic PCR from wild-type (Ax2) and
forC cells.
Amplification of wild-type genomic forC locus yielded a 3.6 kb
product; amplification of the forC knocked-out locus yielded a 2.4 kb
product.
