Protein

Alpha-amylase 1

Gene

amyA

Organism
Dictyoglomus thermophilum (strain ATCC 35947 / DSM 3960 / H-6-12)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

Functioni

This amylase is a highly liquefying-type: oligomers appeared at the beginning of incubation, followed by a graded decrease in the amounts of maltotriose, maltose and glucose in prolonged incubation.

Catalytic activityi

Endohydrolysis of (1->4)-alpha-D-glucosidic linkages in polysaccharides containing three or more (1->4)-alpha-linked D-glucose units.

pH dependencei

Optimum pH is 5.5. Stable above pH 5.5.

Temperature dependencei

Optimum temperature is about 90 degrees Celsius. Highly thermostable. Retains 70% of its maximal activity after heating 1 hour at 90 degrees Celsius, but no decrease in activity was observed within the same time at 80 degrees Celsius.
