The design process of artificial genes encoding AGPase (Lan1_opt) takes place as follows:GlgC gene of e. coli bacteria (V 000281.1, GenBank) are G336D mutation, results instead of glycin by aspartic acid, in addition, a number of different nucleotide sequences designed to better fit the plant which does not affect the process of translation. The structure of the gene after mutation G336D is attached to the top of the 5 ' one paragraph 171-bp coding for signal peptide sequences (including 57 amino acid) protein leads to the chloroplast is derived from the gene encoding the small section of rbcS enzyme ribulose bisphosphate carboxylase-1.5 in Arabidopsis, also top 3 ' tail are additional c-myc (11 amino acids) and KDEL sequence (4 amino aicd) with 48 bp help detect protein reorganisation hybrid methods through Western. In addition, the location of XbaI restriction enzymes are added to the top of the 5 ' position and get to know the top 3 ' added SacI by gene Lan1_opt to facilitate the cut and connects to transplant genes in vector design process to transfer genes into plants.
