Recombinant Human Enteropeptidase/Enterokinase Protein (rp145565) - SDS-PAGE
2 μg/lane of Recombinant Human Enteropeptidase/Enterokinase Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing the band at 46 - 49 (light chain) & 130 - 150 (heavy chain) kDa under reducing conditions and 120 - 150 kDa under non-reducing conditions.
Human enterokinase is synthesized as a single-chain precursor. It must undergo an autocatalytic or intermolecular cleavage to remove a linker peptide, thereby converting into the mature and active heterodimer. This functional form consists of a heavy chain and a light chain connected by a disulfide bond. The simultaneous presence of both the uncleaved precursor and the mature heterodimer in the sample indicates that the recombinant protein preparation is a partially processed mixture.
