Sequence analysis of theArabidopsis ACRfamily.(A)Phylogenetic relationships ofArabidopsisACR proteins and the C-terminal ACT domains ofE. coliGlnD. Full-length amino acid sequences ofArabidopsisACR1 to ACR12 and amino acid residues 708-890 ofE. coliGlnD were aligned by ClustalW2 and the neighbor-joining algorithm was used to obtain the phylogenetic tree.(B)Schematic gene structures ofArabidopsis ACR9toACR12. Exons are shown as black boxes and introns are indicated as solid lines.(C)Schematic diagram ofArabidopsisACR9 to ACR12 proteins. The black boxes indicate the ACT domains.
