NCBI Official Full Name
Glycogen/starch synthases, ADP-glucose type
NCBI Official Synonym Symbols
ATSS1; MOP9.12; MOP9_12; SSI; starch synthase 1; STARCH SYNTHASE 1; SUPPRESSOR OF SALICYLIC ACID INSENSITIVE; SUPPRESSOR OF SALICYLIC ACID INSENSITIVITY 1
NCBI Protein Information
Glycogen/starch synthases, ADP-glucose type
NCBI Summary
SSI is a plastidial enzyme and crucial for the synthesis of normal amylopectin in the leaves of Arabidopsis. The absence of SSI results in a deficiency in the number of shorter glucans which in turn affect the formation and connection of the amylopectin clusters in starch.
