PIacI-B0034-K2275004 (glnA-gudB)

We combined the gudB and glnA gene into pSB1C3 backbone. By SDS-PAGE method, we test the expression of both proteins as well. The gel image shows below, where "WC" indicates whole cell, "S" for supernatant, "P" for pellet, and "C" indicates the control of sample without plasmid.

We can see that the glnA and gudB both expressed in E. coli at the same time. Next, we want to test if the Biobrick can function to convert ammonium to glutamine, so we add different ammonium concentration and use kit to detect the glutamine concentration.

The figure above is the functional test result. When merely adding ammonium, the concentration of glutamine is very low. However, if both harboring the plasmid and adding ammonium, the concentration if glutamine is higher.The second and third bar can show the ability of converting ammonium to glutamine.

Biology and usage:

1. The gene bpsA is expressed in C. glutamicum and carries strong fluxes toward L-glutamate, a precursor of indigoidine. [1]

2. The gene bpsA catalyzes indigoidine formation from two molecules of glutamine in an ATP-dependent manner.[2]

Experimental approach:

1. Integrated sfp into the yeast chromosomal δ-sequences.

2. Codon-optimize Te bpsA gene for expression in S. cerevisiae and genomically integrated into locus ARS1014a under control of the TDH3 promoter and ADH1 terminator using a previously reported, cloning free Cas9 toolkit.

3. Use the conventional lithium acetate method to perform transformations.

4. Use 200 ng pCut_1014a and 500 ng of linear Donor DNA with 500 bp homology to the integration locus ARS1014a.[3]
