| Addtional Information | CATALYTIC ACTIVITY:Endohydrolysis of 1,4-alpha-D-glucosidic linkages in oligosaccharides and polysaccharides.COFACTOR:Binds 3 calcium ions per subunit.SUBUNIT:Monomer.DEVELOPMENTAL STAGE:Production of alpha-amylase is hormonally regulated. Germinating embryos produce the hormone gibberellic acid, which within 10 hours stimulates the aleurone cells covering the endosperm of the seed to produce alpha-amylase. The enzyme then degrades the starch within the endosperm for use by the developing plant embryo.INDUCTION:Type B isozyme mRNA is undetectable in unstimulated cells and increases a hundred-fold after stimulation with gibberellic acid.MISCELLANEOUS:There are at least 4 types of alpha-amylase in barley.SIMILARITY:Belongs to the glycosyl hydrolase 13 family. |
