BBa_K3585003 is a composite part constituting of butyrate synthesis pathway enzymes under constitutive promoter (basic parts BBa_J23100). The butyrate biosynthesis gene cluster can degrade galactose and synthesize butyrate.
BBa_K3585006 is a composite part constituting of constitutive promoter (basic parts BBa_J23100) and LacY gene. LacY codes for beta-galactoside permease which regulates the transport of lactose into the cell. BBa_K3585006 is designed to production of beta-galactoside permease on the cell membrane which enables the cell to use lactose as the carbon source.
