ADG1 （ADP glucose pyrophosphorylase 1)
ADP glucose pyrophosphorylase, abbreviated as AGPase, containing 2 subunits, ADG1 and APL1. ADG1 encodes the small subunit and APL1 encodes the large subunit. The large subunit plays a regulatory role whereas the small subunit (ADG1) is the catalytic isoform responsible for AGPase activity. AGPase catalyzes Glucose-6-phosphate (Glu-6-P) converted to adenosine diphosphate glucose (ADPG), which is a key enzyme in amylose synthesis and catalyzes the first, rate limiting step in amylose biosynthesis.
This gene was cloned into the vector pSB1C3. PCR method was used to identify. Fig.1 shows the result of identification.

When this gene was constructed to the expression vector pETDuet-1, ADG1 protein was expressed. His tag was used to purify ADG1 protein. The identification result was showed in Fig.2
