Enzyme Function | FUNCTION: Chloroplastic alpha-glucanotransferase involved in maltotriose metabolism. Probably uses maltotriose as substrate to transfer a maltosyl unit from one molecule to another, resulting in glucose and maltopentaose. The latter can then be further metabolized to maltose and maltotriose by beta-amylase. Required for normal starch degradation in leaves. {ECO:0000269|PubMed:11359613, ECO:0000269|PubMed:19946617}. |
