A mutant O-GlcNAcase enriches Drosophila developmental regulators

An inactive mutant of a bacterial O-GlcNAc hydrolase was used as an affinity reagent to enrich O-GlcNAc-modified proteins from Drosophila embryos and led to the identification, by MS–proteomics, of O-GlcNAcylated proteins involved in embryogenesis.
