Oxy2 as a transcriptional activator gene for copper uptake in Cryptococcus neoformans.

Abstract excerpt

Cryptococcus neoformans is subject to oxidative attack by host immune cells; consequently, oxidant-resistant mechanisms may be important in pathogenesis. Mutations at the OXY2 locus confer decreased laccase and increased sensitivity to hyperbaric oxygen in the background of the oxyl mutation, but, alone, do not confer sensitivity to oxidants. Because metal deficiency can potentiate or ameliorate sensitivity to...
