Protein O- Mannosyltransferase Isoforms Regulate Biofilm Formation in Candida albicans

Abstract
Five isoforms of protein mannosyltransferase (Pmt) O -mannosylate secretory proteins in Candida albicans. pmt mutants were differentially defective for biofilm formation on plastic in static and flow-through systems, and a Pmt inhibitor blocked early stages of biofilm formation. Conceptually, Pmt inhibition may prevent surface anchoring and biofilm-dependent resistance of fungal pathogens.
