LMPD ID
LMP009840
Gene ID
Species
Arabidopsis thaliana (Arabidopsis)
Gene Name
alpha-amylase 1
Gene Symbol
Synonyms
alpha-amylase-like; AMY1; ATAMY1; F13M23.140; F13M23_140
Alternate Names
alpha-amylase 1
Chromosome
4
EC Number
3.2.1.1
Summary
Predicted to be secreted protein based on signalP prediction. Involved in starch mobilization. Mutants are defective in alpha-amylase activity. (Note: AMY1 has been found in the literature to be referred to as AMY3, which is not to be confused with AMY3/At1g69830).

Comments

Comment Type Description
Catalytic Activity Endohydrolysis of (1->4)-alpha-D-glucosidic linkages in polysaccharides containing three or more (1->4)-alpha- linked D-glucose units.
Cofactor Name=Ca(2+); Xref=ChEBI:CHEBI:29108; Evidence={ECO:0000250}; Note=Binds 3 Ca(2+) ions per subunit. {ECO:0000250};
Developmental Stage Up-regulated during leaf senescence.
Disruption Phenotype Early flowering. {ECO:0000269|PubMed:15637061}.
Function Possesses alpha-amylase activity in vitro, but seems not required for breakdown of transitory starch in leaves. {ECO:0000269|PubMed:17324226}.
Induction By gibberellin, abscisic acid (ABA), heat shock and infection with the bacterial pathogen P.syringae. Not regulated by transition from dark to light. {ECO:0000269|PubMed:15347792, ECO:0000269|PubMed:15927942, ECO:0000269|PubMed:17324226}.
Sequence Caution Sequence=CAB36742.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305}; Sequence=CAB79409.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
Similarity Belongs to the glycosyl hydrolase 13 family. {ECO:0000305}.
Subcellular Location Secreted, extracellular space, apoplast {ECO:0000305|PubMed:17324226}.
Subunit Monomer. {ECO:0000250}.
Tissue Specificity Expressed in leaves, stems, flowers and developing siliques. {ECO:0000269|PubMed:15927942}.
