3 Supplementary Figure Legends Supplementary Figure S1 Specific cleavage of Lys63-linked polyubiquitin chains by the AMSH-LP DUB domain and by full-length AMSH-LP. a, The AMSH-LP DUB domain can cleave Lys63-linked polyubiquitin chains but not Lys48-linked chains. Reaction mixtures were analyzed by SDS-PAGE after 20-hour reactions. b, Full-length AMSH-LP can cleave Lys63-linked polyubiquitin chains but not Lys48-linked chains. In contrast, the USP family DUB, UBPY, can cleave both Lys48- and Lys63-linked polyubiquitin chains. Reaction mixtures were analyzed by SDS-PAGE after 20-hour reactions. Supplementary Figure S2 Comparison of AfJAMM and the AMSH-LP DUB domain. a, Sequence alignment of AfJAMM and the AMSH-LP DUB domain. The secondary structure of AMSH-LP is shown above the alignment. Identical residues are highlighted by red background. Gray, orange, and green bars below the alignment correspond to the JAMM core, Ins-1, and Ins-2, respectively. b, Crystal structures of AfJAMM and the AMSH-LP DUB domain are shown as cartoon models in a similar orientation. Zn 2+ and the coordinating water molecule in the active site are shown as grey and red spheres, respectively. Residues involved in Zn 2+ coordination are shown as stick models. Ins-1 and Ins-2 of AMSH-LP are colored orange and green, respectively. Supplementary Figure S3 Comparison of the DUB domains of AMSH-LP and AMSH. a, Sequence alignment of the DUB domains of AMSH-LP and AMSH from representative organisms. The drawing schemes are the same as in Fig. 5a. b, Conservation of the DUB domains of AMSH and AMSH-LP is mapped on the AMSH-LP surface. The drawing schemes are the same as in Fig. 5b. 3

4 Supplementary Figure S4 The closed active site of AMSH-LP. AMSH-LP and K63-Ub 2 are shown as molecular surface and cartoon representations, respectively. The side chains of Asp321 and Phe407, which cover the active site, are colored orange and green, respectively. The proximal and distal ubiquitins are colored pink and cyan, respectively. Supplementary Figure S5 Cleavage of Lys48-linked polyubiquitin chains by the DUB domain of AMSH-LP mutants Supplementary Figure S6 Sequence alignment of 10 human JAMM proteins (6 DUBs and 4 non-dub proteins). Common sequences for JAMM DUBs are surrounded by rectangles. The secondary structure of AMSH-LP and putative signature sequences (φ; aliphatic residues, X; any residues) are shown above the alignment. MYSM1 has a 23-residue insertion between α3 and β7. Supplementary Figure S7 Sequence alignment of the DUB domains of AMSH-LP, AMSH, and POH1/Rpn11 from the representative organisms The secondary structure of AMSH-LP is shown above the alignment. % and more than 60% identical residues are highlighted by red and yellow backgrounds, respectively. Gray, orange, and green bars below the alignment correspond to the JAMM core, Ins-1, and Ins-2, respectively. Green squares indicate the residues involved in Zn 2+ coordination. Pink and cyan triangles indicate residues that form hydrophobic interactions with the proximal and distal ubiquitins, respectively. Pink and cyan circles indicate residues that form hydrogen bonds with the proximal and distal ubiquitins, respectively. Open circles indicate that only the main chain atoms are involved in the hydrogen bonding, whereas filled circles indicate that only the side chain atoms or both the side chain and main chain atoms are involved in the hydrogen bonding. 4
