    Functioni

    Plays an important role during endosperm starch synthesis. Determines the type of amylopectin structure of starch grain. Synthesizes long B1 amylopectin chains by elongating short A and B1 chains, independently of the other soluble starch synthases. Barely active in japonica subspecies.2 Publications

    Miscellaneousi

    Miscellaneous

    Increased activity due to variations in subspecies indica is associated with the synthesis of the L-type amylopectin, which contains much lower proportion of short amylopectin chains than the S-type amylopectin found in most japonica varieties. The difference in amylopectin chain composition explains why starch from japonica subspecies has a lower gelatinisation temperature than starch from indica subspecies.
