Over expression of E. coli Acetyl- CoA carboxylase (ACC)sub-unit accC in E.coli to enhance fatty acid accumulation for Bio-fuel production”.
PROJECT DESCRIPTION Our gene of interest is accC gene from E. coli 0157:H7 accC gene is the biotin subunit of ACC enzyme which catalyze the biosynthesis of Malonyl CoA. Malonyl CoA controls the rate of fatty acid (Triacylglycerol) biosynthesis. TAG is the fatty acid i.e. used for the biofuel production.In this experiment we will identify if the overexpression of accC gene in E.coli might enhance the production of TAG. For this process we will chttp://openwetware.org/skins/common/images/button_bold.pnglone our gene of interest in to plasmid pSB1A3 and transform it in host E. coli. We will do SDS-PAGE for detection of protein and thin layer chromatography for the quantification of fatty acids.
