The triple auxotrophic transformants were tested for β-galactosidase activity using the filter paper assay described in the manual provided by Clontech.
We selected 25 Arg +transformants and analyzed them by Southern blotting for integration of the UAU1 cassette into one of the two CaCET1 chromosomal loci to yield the heterozygote CaCET1/cacet1::UAU1 configuration depicted in Figure 1. Briefly, genomic DNA was isolated from the 25 Arg +strains, then digested with Sca I (which cuts neither CaCET1 nor UAU1 ). The digests were resolved by agarose gel-electrophoresis and transferred to membranes, which were probed with a radiolabeled DNA corresponding to the 5' segment of CaCET1 (probe A in Figure 1).
Chromosome-size DNA was prepared from yeast transformants carrying circular YACs, separated by clamped homogeneous electrical field gel electrophoresis (CHEF), transferred onto a nylon membrane, and hybridized with an alphoid DNA probe or Alu -probe (see above).
They were unable to recover a homozygous cgt1Δ/cgt1Δ isolate after a second transformation with the URA3 disruption cassette after testing 13 transformants.
The deleted segment contains the catalytic domain essential for triphosphatase activity in vitro and for complementation of the cet1Δ strain of S. cerevisiae [ 10 11 ] . Second, we introduced the linearized deletion allele into a diploid C. albicans ura3/ura3 arg4/arg4 strain and selected for Arg +transformants.
