Bioinformatic indications that COPI- and clathrin-based transport systems are not present in chloroplasts: an Arabidopsis model.

ABSTRACT: Coated vesicle transport occurs in the cytosol of yeast, mammals and plants. It consists of three different transport systems, the COPI, COPII and clathrin coated vesicles (CCV), all of which participate in the transfer of proteins and lipids between different cytosolic compartments. There are also indications that chloroplasts have a vesicle transport system. Several putative chloroplast-localized proteins, including CPSAR1 and CPRabA5e with similarities to cytosolic COPII transport-related proteins, were detected in previous experimental and bioinformatics studies. These indications raised the hypothesis that a COPI- and/or CCV-related system may be present in chloroplasts, in addition to a COPII-related system. To test this hypothesis we bioinformatically searched for chloroplast protei
