Deletion of intra S–S converts NF-8 into two protein assemblies. a Structural design of the Hα subunit of NF-8 that contains an intra S–S bond. b Native PAGE of two overexpressed products related to mutant Δ3C. Lane 1 corresponds to the protein species with the larger MW, while lane 2 represents the protein species with the smaller MW. Source data are provided as a Source Data file. c Sedimentation coefficient distribution of the two products. d TEM image of the protein product with the larger MW. e TEM image of the protein product with the smaller MW. Scale bars represent 50 nm
