Nov 1, 2018 · Here we review the current knowledge of each of the nine Arabidopsis BAMs, including information on their localization, structural features, expression patterns, regulation and potential functions.

We generated a series of double mutants lacking BAM5 and each of the active plastidic enzymes (BAM1, BAM2, BAM3, and BAM6) and found that most of the plastidic activity in 5-week-old plants was encoded by BAM1 and BAM3. Both of these activities were relatively constant during the day and the night.

Aug 14, 2018 · BAM5 is catalytically active, cytosolic and expressed in phloem tissue. Two catalytically inactive BAMs are plastid localized (BAM4 and BAM9) and probably play a regulatory role in starch degradation, and two are nuclear-localized transcription factors (BAM7 and BAM8).

Here, we examined 961 β-amylase sequences from 136 different algae and land plant species, including 66 sequenced genomes and many transcriptomes. The extraordinary number and the diversity of organisms examined allowed us to reconstruct the main patterns of β-amylase evolution in land plants.

Here we review the current knowledge of each of the nine Arabidopsis BAMs, including information on their localization, structural features, expression patterns, regulation and potential functions.

Starch degradation in chloroplasts requires β‐amylase (BAM) activity, but in Arabidopsis, there are nine BAM proteins, five of which are thought to be catalytic. Although single‐gene knockouts revealed the necessity of BAM3 for starch degradation, contributions of other …

arabidopsis thaliana beta-amylase, at-beta-amy, atbeta-amy, bam5, beta-amylase 5, bmy1, ram1, reduced beta amylase 1 Description cytosolic beta-amylase expressed in rosette leaves and inducible by sugar.

Nov 1, 2018 · In this review, we have broken up the discussion of each BAM based on its cellular location and proposed catalytic activity. The relative abundance of BAM5 in Arabidopsis and other species was a key reason that it was the first BAM to be …

Major cytosolic beta-amylase isoform in rosette leaves and inflorescences stems.

Beta-amylase (BAM) is an important starch-hydrolyzing enzyme that plays a significant role in starch degradation and responses to environmental stress. In this study, 21 members of the BAM gene family were identified in the white clover genome.
