Additional file 2: of Arabidopsis Qc-SNARE genes BET11 and BET12 are required for fertility and pollen tube elongation Pablo Bolaños-Villegas Cian-Ling Guo Guang-Yuh Jauh 10.6084/m9.figshare.c.3601925_D3.v1 https://springernature.figshare.com/articles/figure/Additional_file_2_of___Arabidopsis_Qc-SNARE_genes_BET11_and_BET12_are_required_for_fertility_and_pollen_tube_elongation/4335062 Figure S1. The Arabidopsis Qc-SNARE genes BET11 and BET12 encode membrane integral proteins. a Alignment of amino acid sequences with the consistency-based T-Coffee program ( http://www.tcoffee.org ) revealed structural conservation (67.1 %) between the Arabidopsis BET11 and BET12 proteins and the yeast homolog Sft1. The residue color scheme shows the primary library support for the alignment of the considered residue on a scale from 0 (blue, poorly supported) to 9 (dark red, strongly supported). b and c left, diagram of the structural domains of BET11 and BET12 proteins adapted from UNIPROT ( http://www.uniprot.org ). Both proteins feature an N-terminal SNARE coiled-coil domain (red), a C-terminal transmembrane domain (red), and a C-terminal vesicular topological domain (green); however, only BET11 features a phospho-serine at residue 56. Right, 3D structures according to the SWISS-MODEL repository (swissmodel.expasy.org). Both BET11 and BET12 are believed to assemble as single chains that may associate as heterotetramers. Symbols: * = identity match,: = high structural homology,. = high similarity. 2015-09-02 05:00:00 Arabidopsis thaliana SNAREs Fertility Pollen tube elongation
