Figure 2.

Alignment of amino acid sequences of the N termini of T. aestivum plastid ACCase (Tap), Zea mays plastid ACCase (Zmp), B. napus plastid ACCase (Bnp), T. aestivum cytosolic ACCase (Tac), and the biotin carboxylase subunit of Anabaena 7120 ACCase (An). The first conserved amino acid present in all sequences (leucine, shown in boldface) identifies the beginning of the biotin carboxylase domain. The beginning of the mature ACCase (processing site) has not yet been established for any of the plastid ACCases. ∗, Amino acid identity with the T. aestivum plastid ACCase; #, an amino acid identical in all the sequences. Sequence accession numbers are listed in Table 1.
