Human Ovastacin protease phosphomimic_B

Since ovastacin (BBa_K3889024) has a eukaryotic origin, this protein undergoes several Post Translational Modifications (PTMs) including the addition of disulphide bonds and phosphorylation at serine and tyrosine residues. However, the recombinant protein if produced in a prokaryotic organism will lack the necessary machinery to carry out PTMs. Hence, a phosphomimetic variant(s) of ovastacin was made by changing or mutating the serine to aspartic acid and tyrosine to glutamic acid residues at S99, S156, S244 and Y279 (amino acid numbered with reference to pro-ovastacin) respectively.
