Fig. 2: Structures of VcMbnABC and RrMbnABC.

a–b Overall structures of MbnABC complexes, VcMbnABC (a), RrMbnABC (b). MbnA, MbnB and MbnC are shown in different colors. The MbnA shown as ball-and-stick models are contoured with a 2Fo-Fc map at 1 σ. c The TIM barrel of VcMbnB (left) and RrMbnB (right). Red dotted circles denote core pores. d The structure of VcMbnC (left) and RrMbnC (right). NTD and CTD are presented as cartoons. e VcMbnBC and RrMbnBC show nearly identical architectures. f The structures of RrMbnA (upper) and VcMbnA (lower), contoured with a 2Fo-Fc map at 1.5 σ. Sequence alignment of RrMbnA and VcMbnA is shown with conserved amino acids highlighted.
