Sequence alignment of Flaveria bidentis βCA3 withArabidopsis thaliana βCA isoforms
A comparison of the amino acid sequence of Arabidopsis thaliana βCA (AtβCA) isoforms with βCA3 of Flaveria bidentis demonstrates that six isoforms of βCA are present inArabidopsis thaliana, out of which three are cytosolic, two chloroplastic, and one mitochondrial having 57%-72%, 36%-59% and 33% homology with FbβCA3 (see Table S3 ). The catalytic mechanism of the enzyme is highly conserved in the AtβCA’ssequences and FbβCA3 (Fig. S1 ).
