We have cloned a cDNA for vacuolar proton-translocating pyrophosphatase of Chara corallina that is one of the closest
green algae to the land plants. The deduced protein consists of 793 amino acid residues. Its sequence is 71% identical to the
H-pyrophosphatases of land plants, and is less than 46% identical to those of marine alga and phototrophic
bacterium. ß 1999 Elsevier Science B.V. All rights reserved.
