Protein

1,4-alpha-glucan-branching enzyme 1, chloroplastic/amyloplastic

Gene

SBEI

Organism
Pisum sativum (Garden pea)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Catalyzes the formation of the alpha-1,6-glucosidic linkages in starch by scission of a 1,4-alpha-linked oligosaccharide from growing alpha-1,4-glucan chains and the subsequent attachment of the oligosaccharide to the alpha-1,6 position. May preferentially transfer short chains during branching. Responsible for the synthesis of about 75% of the amylopectin found in the starch granules of mature embryos.1 Publication

Catalytic activityi

Transfers a segment of a (1->4)-alpha-D-glucan chain to a primary hydroxy group in a similar glucan chain.1 Publication

Miscellaneousi

Miscellaneous

The wrinkled seeds phenotype (rr) studied by Mendel in 1866 is probably caused by an 800 bp insertion in the SBEI gene, leading to the loss of the last 61 amino acids of the protein and a complete absence of activity.1 Publication
