Updated project metadata. To identify the SUMOylation sites in VdEno, VdEno and SUMOylated VdEno were immunoprecipitated using anti-Flag agarose beads from VdEno/SUMO/Δulpb strain, and separated by SDS gel. The proteins above 55 kDa, which were indicated by marker, were excised and subjected to MS. One putative SUMOylation site (K313) in VdEno was given by MS .
