Fig. 1. Aligned deduced amino acid sequences of the endosperm-specific (Bmy1) and tissue-ubiquitous (Bmy2) ß-amylases from the barley cultivars Morex and Steptoe. Morex Bmy1 is identified as M-Bmy1. Steptoe Bmy1 is identified as S-Bmy1. Morex Bmy2 is identified as M-Bmy2. Steptoe Bmy2 is identified as S-Bmy2. The asterisks label identical amino acids found in all four sequences. The two ß-amylase signature sequences are highlighted. The three single amino acid differences between the two Bmy1 and between the two Bmy2 enzymes are boxed.
