Crystal structure of GvpF. a Cartoon representation of the overall structure. The N-domain, C-domain and C-terminal tail are colored in blue, green and red, respectively. The secondary structural elements are labeled sequentially. b Structural superposition of Anabaena sp. PCC 7120 GvpF (blue) on M. aeruginosa PCC 7806 GvpF (orange; PDB ID: 4QSG). c Multiple-sequence alignment of GvpF from different cyanobacterial strains. The alignment was performed with the program Multalin. The corresponding secondary structural elements of GvpF are displayed above the sequences. All sequences were downloaded from the NCBI database with the following accession numbers: Anabaena sp. PCC 7120, BAB73947; Calothrix sp. PCC 7103, WP_019492269; Nodularia spumigena CCY9414, EAW43904; Microcystis aeruginosa PCC 7806, CAE11906; Cylindrospermopsis raciborskii, WP_085729041; Raphidiopsis brookii D9, EFA73417; Oscillatoria sp. PCC 10802, WP_017721720; Arthrospira platensis, WP_006616264; Pseudanabaena sp. SR411, WP_094529688; Synechococcus sp. PCC 7502, AFY73702
