Figure 2. Biochemical features and activities of DEAD-box helicases.

Figure 2

The inner circle marks the basic biochemical features, RNA, nucleotide (ATP) and protein binding. The yellow arrows mark the connection between the activities. The outer circle segments (light red) designate the activities that arise from either one or the coordination of two basic biochemical features. The red lines indicate which biochemical features contribute to a given activity. RNA structure conversion is based on the coordination between two activities, strand annealing and RNA unwinding, as indicated.
