Figure 7. Acetylation of K909 interacts with K907, but K907 does not interact with viral RNA.

• A
  The structural modeling result of RIG‐I/dsRNA complex and positions of the lysine residue were presented. RIG‐I helicase A and B are shown as green and pale blue ribbons. The dsRNA strands were presented as purple and yellow rods, respectively. Two lysine residues, K907 and K909, on RIG‐I that interact with dsRNA are indicated as violet sticks. K907 forms hydrogen bonding with neither 5′ppp‐dsRNA nor K907.
• B, C
  Acetylated K909 and K907 on RIG‐I are indicated as green sticks. There was hydrogen bonding between NH2 of K907 and oxygen of acetyl‐K909.
