General Information | Comment | Organism |
---|---|---|
malfunction | a mutant lacking starch synthase 4 is impaired in its ability to initiate starch granules, its chloroplasts rarely contain more than one large granule, and the plants have a pale appearance and reduced growth. The chloroplastic alpha-amylase AMY3 abundance is reduced in mutants lacking starch synthase 3 and/or 4 | Arabidopsis thaliana |
metabolism | the enzyme plays a key role in granule initiation, allowing it to proceed in a way that avoids premature degradation of primers by starch hydrolases, such as the chloroplastic alpha-amylase AMY3 | Arabidopsis thaliana |
