Alignment of NCS1-Type Protein Sequences from Different Organisms.
NCS1 proteins from Arabidopsis (PLUTO), S. cerevisiae (FUR4, FUI1, and DAL4), Arthrobacter aurescens (HYUP), Bacillus subtilis (PUCI), and M. liquefaciens (MHP1) were aligned using the ClustalW program of the EMBL European Bioinformatics Institute (www.ebi.ac.uk). Conserved amino acid residues are shown with a black background.
