| disruption of the gene encoding the secreted acid protease (acp) in the yeast candida tropicalis. | the gene for the secreted acid protease (acp), a potential virulence factor of candida species, was inactivated in candida tropicalis by gene disruption. the disruption was performed by cotransformation of an ade2 c. tropicalis mutant with a linear dna fragment carrying a deletion in acp, and the replicative vector pmk16 which carries a selectable ade2 gene marker. few of the transformants exhibited lower protease secretion levels and were shown to have one deleted and one unaffected acp copy, s ... | 1992 | 1526448 |
