Required for intron-independent turnover and processing of mitochondrial RNA. It is a key control element in nuclear-mitochondrial interactions (By similarity). Required for embedded hyphal growth, for wild-type respiratory growth, and biofilm development. Required for chlamydospore formation, distinctive morphological feature of the fungal pathogen C.albicans that can be induced to form in oxygen-limited environments and has been reported in clinical specimens. Plays am important role in virulence. ATP + H2O = ADP + H(+) + phosphate Leads to completely attenuated virulence in a mouse keratitis model.
