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. 2 H(+) + 2 superoxide = H2O2 + O2 Binds 1 copper ion per subunit. Binds 1 zinc ion per subunit. Covalently-linked GPI-modified cell wall protein (GPI-CWP). Induced by farnesol and ciclopirox. Expression is higher in opaque cells compared to white cells. The GPI-anchor is attached to the protein in the endoplasmic reticulum and serves to target the protein to the cell surface. There, the glucosamine-inositol phospholipid moiety is cleaved off and the GPI-modified mannoprotein is covalently attached via its lipidless GPI glycan remnant to the 1,6-beta-glucan of the outer cell wall layer. Belongs to the Cu-Zn superoxide dismutase family.
