Multiple sequence alignment of plant SDH family. ESPript output was obtained with the sequence alignment of plant SDHs and human SDH. Secondary structures were inferred using human SDH (PDB: 1PL8) as a template, with springs representing helices and arrows representing beta-strands. Sequences were grouped into 1 (1PL8 and core Eudicot SDH Class I), 2 (core Eudicot SDH Class II), 3 (A.coerlea SDH) and 4 (monocot SDH). Amino acid site numbering above the alignment is according to LIDH (Q1PSI9) without the first 20 amino acids. Adjacent similarity amino acid sites were boxed in blue frame. Similarity calculations were based on the complete SDH alignments but only partial sequences for SDH Class I and SDH Class II were displayed. The active site residues identified in this study are marked with red triangles. Conserved domains are indicated above the alignment.
