Amino acid sequence alignments of the catalytic
domains of debranching enzymes from barley (Fig. 2), rice (Nakamura et
al., 1996), spinach (A. Renz, R. Schmid, J. Kossmann, and E. Beck,
unpublished data), and K. aerogenes (Katsuragi et al.,
1987), using the PileUp and PrettyBox programs (Devereux et al., 1984).
Shaded and hatched boxes indicate identical and homologous residues,
respectively.
