Kumamolisin-As_S354N, D358G, D368H

A mutated Kumamolisin-As enzyme aimed to combat celiac disease by increased specificity for the PQLP peptide, an antigenic epitope in gliadin.

Usage and Biology

To test BBa _K590024, it was inserted into a pET29b+ vector using [http://2011.igem.org/Team:Washington/Protocols/Kunkel Kunkel Mutagenesis]. Kumamolisin-As was then produced and purified as described in the [http://2011.igem.org/Team:Washington/Protocols/50mL_UW 2011 iGEM Team's Small Scale Protein Expression and Purification Protocol]. The purified protein was then tested for activity. For a detailed description of the assay, please see the [http://2011.igem.org/Team:Washington/Protocols/Purified_Enzyme_Assay 2011 UW iGEM Purified Enzyme Assay Protocol]. The resulting data is shown below.
