Figure 3. The NL1-NX1β interface.

Figure 3

(a) Side view. NL1 and NX1β backbones are shown as coils. The sidechains of the important residues in NL1-NX1β interaction are shown as sticks. Waters and the Ca2+ are shown as red balls. The position of NX1β splice site 4 is shown as a cyan square, and is near the salt bridge between NL1 Asp387 and NX1β Arg232. (b) View from the NL1 direction. The position of NL1 splice site B is shown as a pink square, and is near the salt bridge between NL1 Glu297 and NX1β Arg109.
