TGG1 and TGG2 from wild-type plants are N-GlcNAc modified. A, Immunoblot detection of TGG1 and TGG2 from wild-type (WT) and triple mutant plants following treatment with or without PNGase F. PNGase F treatment removes high-Man glycans, which increases the rate of TGG1 and TGG2 migration during electrophoresis (Ueda et al., 2006). B, Immunoblots showing the effect of PEGylating wild-type and triple mutant proteins after treatment with or without PNGase F. Asterisks indicate the PEGylated proteins.
