The y-axes of Fig. 3a,b,d in this manuscript were labeled incorrectly. The correct unit for the PDGS activity in these panels should be μmol min−1 mg−1 protein. Additionally, the GST labels were incorrectly represented in Fig. 3c: s-GST should be σ-GST, a-GST should be α-GST; m-GST should be μ-GST; and p-GST should be π-GST. The authors apologize for any inconvenience this may have caused.
