Signature and predicted structure of Agenet/Tudor Domain from Arabidopsis proteins. a Alignment of Agenet/Tudor sequences from Arabidopsis showing the canonical conserved residues analyzed by WebLogo. The highly conserved residues are represented as larger letters in the sequence. Although very diverse, some key-positions contain conserved amino acids and possibly maintain the conserved secondary structure observed. b Multiple sequence alignment of Agenet/Tudor domain sequences from plant proteins: the alignment was performed using Multalin and the result submitted to ESPript server to plot the secondary structure information of the conserved domains over their primary sequence. On the secondary structure displayed, 310-helices are represented as small squiggles (Ƞ), β-strands are rendered as arrows, and strict β-turns (TT). On the primary sequence alignment, the red characters represent similarity of the amino acid residues in the same group of one column and the blue frame represents the similarity across groups. The sequences used for structural analysis and computer modeling were chosen to represent all clades of plants: Gymnosperm Picea abies MA_20337g0010; Angiosperm Monocot Oryza sativa Os05g04180; Angiosperm Eudicot Populus trichocarpa Potri_018G030500_5, Brassica rapa Bra022578, Manihot esculenta cassava4_1_003152, A. thaliana AT3G62300, AT5G13020. The two sequences of Agenet/Tudor repetitions from AIP1 were used (AT3G62300.1 and AT3G62300.2). c Overlapping Agenet/Tudor models generated in the I-TASSER server. The structures are colored in white (B_MA_20337g0010), purple (I_ENT_Potri_018G030500_5), firebrick (I_Central_Bra022578), orange (I_Multiple_Os05g04180), blue (I_BAH_cassava4_1_003152), cyan (D_DUF_AT3G62300.1), yellow (D_DUF_AT5G13020), and green (D_DUF_AT3G62300.2)
