Abstract:
For Ca(2+) to function as a second messenger in signal transduction, it is essential that plant cells maintain low cytoplasmic Ca(2+) levels relative to internal organelles and the apoplast. At the plasma membrane, Ca(2+) is actively transported out of the cytoplasm and current evidence supports the involvement of a primary Ca(2+)-translocating ATPase in mediating this energy-dependent process. This review examines the preliminary biochemical characterization of this transport enzyme.

Protein Transport to the Outer Chloroplast Membrane
Two models describe the mechanism of precursor recognition and entry across the outer membrane through the TOC complex. Model 1 suggests the newly synthesized precursor binds to the TOC receptor 159 and forms a complex.
