Protein
Beta-amylase 1, chloroplastic
Gene
BAM1, BMY7, TRBAMY, At3g23920, F14O13.12
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Beta-amylase activity. Can use p-nitrophenyl maltopentaoside (PNPG5) as substrate only in reduced form. Can play a minor role in the starch degradation and maltose metabolism in chloroplasts during the night. More active on phosphorylated glucan. Interacts directly with starch or other alpha-1,4-glucan.3 Publications

Catalytic activityi

Hydrolysis of (1->4)-alpha-D-glucosidic linkages in polysaccharides so as to remove successive maltose units from the non-reducing ends of the chains.

Enzyme regulationi

Redox regulation; active in reducing conditions, inactive in oxidizing conditions. Thioredoxins f1, m1, and y1 mediate the reversible reductive activation of oxidized BAM1.1 Publication

pH dependencei

Optimum pH is 6-8.3 Publications
