additional information Arabidopsis thaliana glucan debranching occurs primarily at the granule surface via ISA3, but in its absence soluble branched glucans are debranched in the stroma via limit dextrinase. Isoamylase acts at the surface of the starch granule. Atisa3 mutants have more leaf starch and a slower rate of starch breakdown than wild-type plants ?
