Protein: Cell surface superoxide dismutase [Cu-Zn] 4 (EC 1.15.1.1) (GPI-anchored protein 2) (Q5AD05)
Organism: Candida albicans (strain SC5314 / ATCC MYA-2876) (Yeast)
Function: Superoxide dismutases serve to convert damaging superoxide radicals, a key form of ROS, to less damaging hydrogen peroxide that can be converted into water by catalase action. Degrades host-derived reactive oxygen species to escape innate immune surveillance. Involved in the occurrence of miconazole-tolerant persisters in biofilms. Persisters are cells that survive high doses of an antimicrobial agent.
Subcellular location: Secreted, cell wall {ECO:0000269|PubMed:15302828}. Membrane {ECO:0000305|PubMed:15302828}; Lipid-anchor, GPI-anchor. Note=Covalently-linked GPI-modified cell wall protein (GPI-CWP). {ECO:0000269|PubMed:15302828}.
