Abstract excerpt

The vacuolar Zn(2+)/H(+) antiporter of Arabidopsis thaliana, AtMTP1, has a long cytosolic histidine-rich loop. A mutated AtMTP1 in which the first half of the loop (His-half) was deleted exhibited a 11-fold higher transport velocity in yeast cells. Transgenic lines overexpressing the His-half-del...
