WebJun 20, 1995 · We have previously shown that the enzyme phosphomannose isomerase (PMI) is essential for the biosynthesis of Candida albicans cell walls. In this study, we find that PMI can be inhibited by silver ions.
WebThe phosphomannose-isomerase is encoded by the manA gene from Escherichia coli and catalyzes the conversion of mannose-6-phosphate to fructose-6-phosphate, an intermediate of glycolysis. Transformed cells expressing the manA gene can therefore utilize mannose as a carbon and survive on media containing mannose. The manA gene along with a beta ...
