Sequence alignments of the conserved regions (1–5) of CauloGA with other GAs and GDase. The sequences aligned are: CauloGA, C. crescentus CB15 glucoamylase; ClostGA, Clostridium sp. G0005 glucoamylase; TtGA, T. thermosaccharolyticum glucoamylase; TtcGA, T. tengcongensis glucoamylase; AawGA, A. awamori glucoamylase; AgGDase, A. globiformis I42 glucodextranase. The symbol “#” denotes putative catalytic residues. Identical amino acid residues common to three or more of these enzymes are shaded.
