Parts

MsbA:

1.ATP-binding cassette (ABC) transporters MsbA （self-expression system with T7 promoter）

Function

ATP-binding cassette (ABC) transporters are integral membrane proteins that translocate a wide variety of substrates across cellular membranes and are conserved from bacteria to humans. This ABC transporters MsbA can transport fatty acids out of the cell.

Usage and Biology

The RBS and T7 promoter are in front of the MsbA coding sequence and T7 terminator is after MsbA. You can only use this part in E.coil BL21(DE3) or choose other parts we offer in other strains.

Function

ATP-binding cassette (ABC) transporters are integral membrane proteins that translocate a wide variety of substrates across cellular membranes and are conserved from bacteria to humans.this ABC transporters MsbA can transport fatty acids out of the cell.

Usage and Biology

The RBS and FadD promoter are in front of the MsbA coding sequence and T7 terminator is after MsbA. The FadD promoter is sensitive to the concentration of fatty acid. Due to the over expression of MsbA can be harm to the growth of E.coli, it is activated only when the fatty acid concentration is high to lower the toxicity of MsbA.

BTE:

1.ACP Thioesterase BTE

Function

Acyl carrier protein (ACP) thioesterase catalyzes the hydrolysis of acyl-ACP into fatty acid and ACP. This reaction removes the coupling between fatty acid biosynthesis and phospholipid biosyntheis, which is a key to obtaining free fatty acids. This thioesterase BTE can produce fatty acids with 12~14 carbon chain length. In previous reserches, thioesterase gene BTE can be expressed in E.coil BL21(DE3) and enhance the synthesis of free fatty acids.

Usage and Biology

This part can increase the productivity of free fatty acids. However,this part can not express itself. You should add promoter, RBS and terminator to it or using other parts we offer.

2.ACP Thioesterase AtFatA(self-expression system with T7 promoter)

Function

Acyl-acyl carrier protein (ACP) thioesterase catalyzes the hydrolysis of acyl-ACP to fatty acids and ACP this reaction removes the coupling between fatty acid biosynthesis and phospholipid biosyntheis,which is a key to obtain free fatty acids. This thioesterase AtFatA can produce fatty acids with 16~18 carbon chain length. In previous researches, thioesterase gene AtFatA can be expressed in E.coil BL21(DE3) and enhance the synthesis of free fatty acids.

This thioesterase can express itself with a T7 promoter.

Usage and Biology

The RBS and T7 promoter are in front of the AtFatA coding sequence and T7 terminator is after AtFatA. You can only use this part in E.coil BL21(DE3) or choose other parts we offer in other strains.

3.ACP Thioesterase AtFatA(with a promoter absent)

Function

Acyl-acyl carrier protein (ACP) thioesterase catalyzes the hydrolysis of acyl-ACP to fatty acids and ACP this reaction removes the coupling between fatty acid biosynthesis and phospholipid biosyntheis,which is a key to obtain free fatty acids. This thioesterase AtFatA can produce fatty acids with 16~18 carbon chain length. In previous researches, thioesterase gene AtFatA can be expressed in E.coil BL21(DE3) and enhance the synthesis of free fatty acids.

This thioesterase can not express itself .

Usage and Biology

The RBS is in front of the AtFatA coding sequence and T7 terminator is after AtFatA. You can design your own promoter for this part, but use this part in E.coil BL21(DE3) only or you’d better delete the T7 terminator.

4.ACP Thioesterase AtFatA(regulated-expression system with lac promoter)

Function

Acyl-acyl carrier protein (ACP) thioesterase catalyzes the hydrolysis of acyl-ACP to fatty acids and ACP this reaction removes the coupling between fatty acid biosynthesis and phospholipid biosyntheis,which is a key to obtain free fatty acids.In before study, thioesterase gene AtFatA can express in E.coil BL21(DE3),and increase free fatty acids.

This thioesterase can be expressed in the presence of lactose or IPTG.

Usage and Biology

The RBS and lac promoter are in front of the AtFatA coding sequence and T7 terminator is after AtFatA. We can activate the expression of AtFatA by adding lactose in the culture in the absence of glucose.You can only use this part in E.coil BL21(DE3) because the lac promoter we use is the hybrid of lac promoter and T7 promoter.

FabB regulated GFP and FadD regulated RFP

Function

FabB promoter and FabD promoter reacts differently to the changing in concentration of fatty acids. We activate the expression of GFP and RFP by FabB promoter and FabD promoter respectively. When fatty acid concentration fluctuates, the changing in the expression of GFP and RFP tells us the fluctuation of fatty acid concentration.

Usage and Biology

This part functions as a biosensor. In the abundance of fatty acid, the red fluorescence is bright. On the contrary, in the absence of fatty acid, the green fluorescence is bright.
