Subcellular localization
- Unlike the amyloplast resident marker enzymes BEI and BEIIb, which were detected in both the stroma and starch fractions or the starchlocalized GBSSI, only trace amounts of Pho1 were starch bound (Figure 2). Hence, Pho1 is restricted to the stromacompartment of the amyloplasts. A stroma location was also observed for maize endosperm Pho1[1].
