endo-beta-1,3-1,4 glucanase (BglS) from Bacillus Subtilis 168

BglS This gene encodes an endo-beta-1,3-1,4-glucanase (bglS), which is from the bacterium Bacillus subtilis subtilis 168. The enzyme will hydrolyze and thereby cleave internal 1,4 linkages adjacent to 1,3 linkages.

BglS

Usage and Biology The substrates vulnerable to the bglS encoded enzyme are mixed linked beta-glucans. These glucans would have 1,3 and 1,4 beta linkages within the polysaccharide linking together the glucose monomers. Examples of these glucans can be found in oats, maize, and barley.

yesZ The enzyme acts on the terminal end of side chains of Rhamnogalacturonan I Pectin, releasing the free galactose. This gene has been isolated from the bacterium Bacillus subtilis subtilis 168. The enzyme yesZ has beta-galactosidase (beta-galacturonidase) activity, cleaving (1→4)-β-D-galactans to produce single galactose molecules from RG I Pectin.

Usage and Biology Pectin is a component of the primary cell wall of plants. As galactose can be metabolized by the human body and by animals, it is an alternative to the usual target of nutrition/energy boosts in biotechnology, glucose.

These are the three essential parts prtD, prtE, prtF, that make up the Type I secretion system from Erwinia chrysanthemi.This part is made of 3 genes: prtD, prtE, and prtF, that constitute a type I Erwinia chrysanthemi secretion system. The Pump is expressed from a strong constitutive promoter, BBa_k206000, and has the translational terminator BBa_B0014. In pSB1C3.

Used to secrete proteins containing prtB C-terminal tag. The prtB C-terminal tag is built into the protein generator [BBa_K215002]. Any protein of interest can be inserted into the protein generator and then secreted when used in conjunction with this secretion system.

For full characterization data on this part, please see the University of Washington 2009 iGEM project page and Wisconsin Lutheran College 2013 iGEM project page.

This construct is designed for the expression of an already descibed engeneered antinorovirus (NoV) monoclonal antibody (mAb 54.6) in fusion with LPP-OmpA. The antibody is expressed in a single chain fragment variable (scFv) format containing light (VL) and heavy (VH) variable domains separeted by a flexible peptide linker. It has already been reported that the scFv 54.6 binds a native recombinant NoV particles (VLPs) and inhibits VLP interaction with cells. LPP-OmpA functions as a leader sequence and an anchor to display the scFv ot the bacterial surface.The construct consistes of T5 Lac Operator (Bba_K875002), ribosomal binding site, LPP-OmpA-scFv 54.6 antinorovirus, Histidine tag (6HIS), Terminator (B0015).

The part combines a strongly expressed secretion pump with a antinoroviral antibody that is expressed in the outer-membrane can/will be combined with BBa_K1175012 A composite part formed between BBa_K206000 strong pBAD promoter, BBa_B0034 strong RBS, and BBa_K215001 a purification and secretion tag.
