The sGN/sGN∆V8 asymmetric unit contains four molecules organized in two types of dimers. (A) The sGN/sGN∆V8 asymmetric unit (gray box) shows dihedral symmetry (D2) composed of two type of dimers, a noncovalent dimer (A–B and C–D interfaces) and disulfide linked dimers (A–D and B–C interfaces). (B) The unique interactions of the leucine residues at the tips of the pincer. Color scheme is as before. Light colors (light red, pale yellow, and pale cyan) represent the reciprocal protomer in the dimer. (C) Multiple sequence alignments at the PD region show that L177 and L195 are conserved. MUSCLE (52) was used for the multiple alignment of tospovirus GN, including TSWV (APG79624.1), CSNV (BAF62146.1, chrysanthemum stem necrosis virus), ANSV (AYJ76754.1, alstroemeria necrotic streak virus), TCSV (AAU10599.2, tomato chlorotic spot virus), GRSV (AAU10600.2, groundnut ringspot virus), ZLCV (BAF62147.1, zucchini lethal chlorosis virus), INSV (AFP20544.1, impatiens necrotic spot virus), MSMV (YP_009346016.1, melon severe mosaic tospovirus), BNMV (YP_006468902.1, bean necrotic mosaic virus), and SVNV (AMB72701.1, soybean vein necrosis virus).
