SUMMARY PARAGRAPH for ERG7

ERG7 encodes lanosterol synthase, which catalyzes the cyclization of squalene 2,3-epoxide, a step in the biosynthesis of ergosterol (6, 5, 7, 3, 4). Deletion of ERG7 is lethal; an erg7 hem1 (heme-deficient) mutant is auxotrophic for sterols (8). The erg7 null phenotype can be suppressed by expression of the Candida albicans ERG7 gene(9). Expression of ERG9, which encodes farnesyl-diphosphate farnesy l transferase, is increased in erg7 mutants (10).
