Supplemental Figure 1. In vitro ubiquitylation assay with ubiquitin
variants. The ubiquitylation complex consisting of GST-RGLG2, MMZ2
and UBC35 can form ubiquitin chains with WT ubiquitin (left panel),
with ubiquitin variant ub K48R, in which Lys 48 was replaced by Arg
(middle panel), but not with ubiquitin variant K63R, in which Lys 63
was replaced by Arg (right panel), underlining the specificity for ub
chains linked via Lys 63. Reaction conditions were similar to Figure 2,
but a different anti-ubiquitin antibody (Bachmair et al., 1990) was
used for detection.
