Extended Data Fig. 5: Structural features of SID-1.
From: Structural insights into double-stranded RNA recognition and transport by SID-1
a, Topology of SID-1. SID-1 is colored from blue to red. Secondary structural elements are labelled. b, Structure of SID-1 monomer. c, Superposition of ECDI and ECDII. d, A cut-open surface representation of SID-1 TMD. e and f, Two short α-helices mediate the connection between ECDII and TMD. ECDI, ECDII, and TMD are colored in blue, pink, and green, respectively. Key residues on α5 and α6 shown side-chains in sticks. Red dashed lines indicate polar interactions.
