PLANT ACIDIC PEPTIDE N-glycanase (aPNGase) release N-glycans from glycopeptides during the degradation process of glycoproteins in developing or growing plants. We have previously developed a new method to detect the aPNGase activity in crude extracts, which is prerequisite for the construction of aPNGase knockout or overexpression lines. However, this method has the disadvantage of requiring de-sialylation treatment and a lectin chromatography. In this study, therefore, we improved the simple and accurate method for detecting aPNGase activity using anion-exchange HPLC requiring neither the desialylation treatment nor the lectin affinity chromatography.
