We have worked hard to demonstrate that this part enables bacteria to produce L-aspartate, but failed to do that. In the previous works (1), the amount of L-Asp was determined by HPLC. We, however, were unable to use this machinery, so we tried to detect it through alternative method, ninhydrin assay and ultraviolet-visible spectroscopy. For experimental details, see [http://2011.igem.org/Team:UT-Tokyo |our result page].
