Application

5-Fluoroorotic acid hydrate has also been used as a counter-selection agent to screen L. lactis (multi) peptidase knockout mutants and C. albicans. It has been used in synthesis of 5-fluoroorotidine 5′-monophosphate (FOMP).
Useful in the selection of orotidine-5′-phosphate decarboxylase mutants of Saccharomyces cerevisiae.

Biochem/physiol Actions

The diploid budding yeast Candida albicans harbors unique CENPA-rich 3- to 5-kb regions that form the centromere (CEN) core on each of its eight chromosomes. The epigenetic nature of these CENs does not permit the stabilization of a functional kinetochore

Fungal infections by drug-resistant Candida albicans pose a global public health threat. However, the pathogen's diploid genome greatly hinders genome-wide investigations of resistance mechanisms. Here, we develop an efficient piggyBac transposon-mediated mutagenesis system using stable haploid C. albicans to conduct
