Figure 2. Grad‐seq predicts complexes.

• A
  Profiles of 102 proteins < 20 kDa that show fast sedimentation, indicating involvement in complexes.
• B
  Heat map of migration profiles of 77 proteins with the UniProt keyword “RNA‐binding”. For clarity, they were assigned to functionally related classes of RBPs. Note that SP_2040 was added due to its interaction with SP_0776 in the KhpA/B heterodimer (Zheng et al, 2017; Winther et al, 2019), even though it does not have the keyword on UniProt.
