pGal1,10-SNF1

This pGal1,10-SNF1 is a composite biobrick. pGal1, 10-SPT5-Streptavidin Binding Protein(SBP) plasmid, containing 2u origin of replication (ORI) for yeast to start DNA replication, and ORI for bacteria DNA replication, was sponsored by Dr. Tien-Hsien Chang, at Genomics Research Center, Academia Sinica, in Taipei Taiwan. This plasmid can be transformed into bacteria and yeast, which was beneficial for our team to finish making biobricks in bacteria and perform the functional assay in yeast. Our team made 5 different basic parts (one promoter and 4 coding regions) and 4 different composite parts by inserting those 4 basic parts (BBa_K4180000, BBa_K4180002, BBa_K4180003, and BBa_K4180004) to replace the original SPT5 gene.

Galactose promoter can be induced in the presence of galactose and express SNF1(FL) ; SNF1 in yeast is homology of AMPKα in human, which is a major metabolism sensor protein of the whole metabolic pathways, increasing catabolic process, such as triggering fatty acid catabolism for more ATP, and reducing anabolic process, such as protein and fatty acid synthesis to reduce energy consumed.
