Other claims from this paper (8)
- Observation Seven alpha-amylase isoenzymes were purified from quiescent Araucaria seeds.
- Observation The seven isoenzymes had masses of 45.7, 47.0, 50.2, 51.2, 52.0, 53.5 and 55.2 kDa.
- Method / resource The two main isoforms were separated chromatographically from each other and other isoenzymes.
- Observation The isoenzymes are rich in glycine, aspartic acid/asparagine, alanine, serine, proline and glutamic acid/glutamine.
- Observation The three sequenced isoenzymes had identical N-terminal sequences.
- Observation Composition and N-terminal sequence comparisons found no relation to cereal and Vigna radiata alpha-amylases.
- Observation Barley alpha-amylase antibodies cross-reacted with all Araucaria alpha-amylases.
- Observation Peptide maps suggested genetic differences among Araucaria isoenzymes.
