Micro-liquid-chromatography–electrospray-mass-spectrometry analyses of glycopeptides from acid phosphatase and α-galactosidase that are monoglucosylated by UDP–glucose glycoprotein:glucosyltransferase. Analyses were carried out as described for Fig. 2B. GT, Glu-C–trypsne combined digest; Rel. int., relative ion intensity; T, trypsin digest.
