Localization of phytochelatins in fungi

The small, cysteine-rich peptides called phytochelatins (PCs) are the
most important heavy metal binding peptides in plants. They are also
found in some fungi (S. cerevisiae, N. crassa, S. pombe and C.
glabrata) and animals. Most of the research, however, has been done
with plants.

In plants, the PCs are translocated to the vacuole after the binding
of heavy metals. But fungi and animals don't have vacuoles. Where are
the PCs located after binding the metals in these organisms??
