Two genes isolated from Schwanniomyces
occidentalis, ENA1 and ENA2, encode
P-type ATPases highly homologous to the Na-ATPases of
Saccharomyces cerevisiae and complement the Na+
sensitivity of an S. cerevisiae mutant strain lacking its
own Na-ATPases. The expression of both ENA1 and
ENA2 was highly dependent on a high external pH, but
whereas a high pH was sufficient for the expression of
ENA2, the expression of ENA1 required a high pH
and the presence of Na+. Disruption of ENA1
rendered the cells less tolerant to Na+ than the wild-type
strain and decreased their capacity for Na+ extrusion.
Disruption of ENA2 did not affect Na+
tolerance, but decreased both the growth at high pH and K+
efflux. We discuss these results and propose that fungal Na-ATPases should be considered alkali cation ATPases. By sequence comparison, we
found that fungal Na-ATPases form a homogeneous group that can be
distinguished from other cation-pumping P-type ATPases, except from the
cta3 Ca-ATPase of Schizosaccharomyces pombe.
