AtPU1 Sequence Data
TAIR Locus ID: AT5G04360
The genomic sequence analyzed spans nucleotides 1,221,301 - 1,228,800 on the forward strand of chromosome 5.
A full length cDNA is not available for this gene, so many of the intron/exon junctions have not been directly confirmed. The 5'- and 3'-untranslated regions noted in blue text are confirmed by EST sequences.
Isoform identification: Homology comparisons indicate definitively that AtPU-1 codes for a pullulanase-type DBE, and that there is only one such enzyme coded for by the Arabidopsis genome. The nearest homologs are the isoamylase-type DBEs, although the product of AtPU-1 is much closer to pullulanase-type DBEs in other plants and in procaryotes than it is to the isoamylase-type DBEs of Arabidopsis.
Note on gene names: At this time we are using Project ID numbers as placeholders for specific gene names. There is no relation between the Project ID number and a particular enzyme subfamily.
