1.B.29.1.4
Oep21 of 167 aas is a voltage-dependent rectifying anion channel
that facilitates the translocation between the chloroplast and cytoplasm of
phosphorylated carbohydrates such as triosephosphate, 3-phosphoglycerate
and inorganic phosphate (Pi), depending on the ATP to triosephosphate ratio
in the plastidial intermembrane space; in high triosephosphate/ATP
conditions (e.g. photosynthesis), export of triosphophate from
chloroplasts occurs (outward rectifying channels), but in high
ATP/triosephosphate conditions (e.g., the dark phase), import of
phosphosolutes occurs (inward rectifying channels).
