Fig. 1. Overall structure of the PB1 domain of NBR1
(1–85). (A) Ribbon representation. The type-A PB1 domain
residues Asp-50, Glu-52, Glu-54, and Glu-63 are shown in
ball-and-stick representation; (B) Electrostatic potential
surface of the NBR1 PB1 domain; red indicates negatively charged
surface areas and blue indicates positively charged surface
areas. The acidic cluster A1 is comprised of Asp50, Glu52, and
Glu54; A2 is comprised of Asp63.
