LDA limit dextrinase [Arabidopsis thaliana (thale cress)] - Gene

Summary

Official Symbol: LDA
Official Full Name: limit dextrinase
Primary source: TAIR:AT5G04360
Locus tag: AT5G04360
See related: Araport:AT5G04360
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Arabidopsis thaliana (ecotype: Columbia)
Lineage: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis
Also known as: ATLDA; ATPU1; limit dextrinase; LIMIT DEXTRINASE; PU1; PULLULANASE; PULLULANASE 1; T19N18.90; T19N18_90
Summary: Encodes an enzyme thought to be involved in the hydrolysis of the alpha-1,6 linkages during starch degradation in seed endosperm. However, a knockout mutant of Arabidopsis lacking limit dextrinase has normal rates of starch degradation in the leaf at night, indicating that more than one isoamylases might be involved in this process.
