Fig. 2

MSA of conserved regions of PDATs from algae and examples from other representative taxa. The black line represents A. thaliana PDAT, arrows and asterisks point to important amino acids within the structurally conserved elements: the so-called lid region, the salt bridge and the catalytic triad, based on human LCAT [43, 44] and the analysis of plant PDATs done by Pan et al. [33]. Sequence order corresponds to MAFFT alignment. Species are indicated with their internal codes, first letter of the genus and first three letters of the species (see Additional file 1 for details). IDs correspond to Uniprot IDs when available or to specific genome IDs when the sequence was not found in Uniprot. (Tr) indicates that the corresponding sequence is truncated in any of the conserved structural elements
