GBSS1 (Granule-bound starch synthase1)

GBSS1 (Granule-bound starch synthase1) is another key enzyme for the amylose synthesis. It belongs to UDP-Glycosyltransferase superfamily protein. GBSS1 is an enzyme that catalyzes the transfer of glucose from to glucose-containing polysaccharides with α1,4-linkages, which is the main gene controlling amylose synthesis.

When GBSS1 gene was constructed to the expression vector pET-28a(+), GBSS1 protein was expressed. His tag was used to purify GBSS1 protein. The identification result was showed in Fig.2
