We used Thermo Excalibur ProMass to calculate the molecular excess weight of this fragment in the presence and absence of Pex15 after deuteration for 0, 15, and 600?s?(Supplementary Table 2). For experiments shown in Fig.?3a and Supplementary Number?7, we incubated 30?M Pex15 1-309 with 2?M Pex1/Pex6?hexamer or buffer for Lumicitabine 60?s at 30?C with 30?mM […]
