Fig. 2: Structures of A, B, and C cylinders, including terminal emitters and linker proteins.
From: Core and rod structures of a thermophilic cyanobacterial light-harvesting phycobilisome
a Arrangement of the terminal emitters (αLCM of ApcE [LCM] and ApcD), ApcF, and linker proteins (ApcE [LCM] and ApcCs). b Structures of APC trimer (A3) and Rep1 of ApcE (LCM) in A cylinder. c Structures of APC trimers A1 and A2, ApcC, and Rep2 of ApcE (LCM) in A cylinder. d Structures of APC trimers B1 and B2, ApcC, Rep3, and Arm3 of ApcE (LCM) in B cylinder. e Structure of APC trimers C1 and C2, ApcC, and Rep4 of ApcE (LCM) in C’ cylinder. f Superposition of four Rep structures (Reps1–4). Dashed lines indicate the α-helixes in the Rep regions. Rep1, green; Rep2, red; Rep3, blue; Rep4, cyan.
