Part:BBa_K1789000
IaaM
This part is the coding sequence of tryptophan-2-mono-oxygenase.
Usage and Biology
Indole-3-acetic acid (IAA), also known as auxin, is a plant hormone, which can promote growth and protect the soil from erosion. IAA can be synthesized through IAM pathway, originated from Pseudomonas savastanoi. Two important enzymes are contained in this pathway, AKA IaaM and IaaH.
IaaM is the tryptophan-2-mono-oxygenase. This enzyme catalyzes the oxidative carboxylation of L-tryptophan to indole-3-acetamide. IaaH is the indoleacetimide hydrolase. This enzyme catalyses the hydrolysis of indoleacetamide to indoleacetate and ammonia. This pathway is relevantly easy to be expressed in prokaryotic cells, and its substrate (Trp) can be synthesized by host cells.

Experimental Validation
This part is validated through three ways: PCR, Sequence, and functional testing
PCR
Methods
The PCR is performed with Premix EX Taq by Takara.
F-Prime: 5'-GAACCTCTTACGTGCCCGATCAA-3'
R-Prime: 5'-CGCCGCAGCCGAACGAC-3'
The PCR protocol is selected based on the Users Manuel. The Electrophoresis was performed on a 1％ Agarose glu.
Results
The result of the agarose electrophoresis was shown on the picture above.
Functional Test
This part is tested together with the part BBa_K1789001, in the device BBa_K1789022.
The result shows that this part can work as expected to generate IAA together with IAAH.
