Abstract excerpt

Protein transport to peroxisomes requires various proteins, such as receptors in the cytosol and components of the transport machinery on peroxisomal membranes. The Arabidopsis apem (aberrant peroxisome morphology) mutant apem7 shows decreased efficiency of peroxisome targeting signal 1-dependent protein transport to peroxisomes. In apem7 mutants, peroxisome targeting signal 2-dependent protein transport is also...
