Human Ovastacin protease phosphomimic_A

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 machinary to carry out PTMs. Hence, a phosphomimetic variant(s) of ovastacin was made by changing or mutating the serine to aspartic acid S99, S156 and S244 (amino acid numbered with reference to pro-ovastacin) respectively.
