Alpha-amylase inhibitor protein, which inhibits the activity of insect (Callosobruchus analis) α-amylase, was characterized from V. sublobata. The molecular weight of purified inhibitor protein was 14 kDa by SDS-PAGE. The inhibitor is non-glycosylated protein and its N-terminal sequence is similar (A P S P V...) to Phaseolus vulgaris α-AI-1. Its pI value is 6.0 and largely localised in cotyledo...
A new wheat dimeric alpha-amylase inhibitor, designated WDAI-3, has been characterized. WDAI-3 is a homodimeric protein active against alpha-amylase from human saliva and from the insect Tenebrio molitor, but inactive against that from pig pancreas or against trypsin. Its N-terminal amino acid sequence is closer to those of the wheat dimeric inhibitors 0.19 and 0.53 (89-91% identical positions ...
Insect pests are highly dependent on starch-rich cereals and cause severe damage to the cereal grain nutrient yield. Amylase trypsin inhibitor protein degrades digestive enzyme alpha-amylase which plays a key role in carbohydrate metabolism as well growth development of insects. These proteins mainly found crops like wheat, maize, barley rich sources starch. Due defensive mechanism against pest...
The inhibitory activity on pancreatic α-amylase by cyanidin-3-rutinoside was examined in vitro. The IC₅₀ value of cyanidin-3-rutinoside against pancreatic α-amylase was 24.4 ± 0.1 μM. The kinetic analysis revealed that pancreatic α-amylase was inhibited by cyanidin-3-rutinoside in a non-competitive manner. The additive inhibition of a combination of cyanidin-3-rutinoside with acarbose against p...
Diabetes is known as a multifactorial disease. The treatment of diabetes is complicated due to its inherent pathophysiological factors related to the disease. One of the complications of diabetes is postprandial hyperglycemia. Glucosidase inhibitors, particularly ?-amylase inhibitors can help manage postprandial hyperglycemia. The low molecular weight inhibitor of ? -amylases called PAMI (pepti...
We report the characterization and cDNA cloning of two alpha-amylase isozymes from larvae of the Western corn rootworm (Diabrotica virgifera virgifera LeConte). Larvae raised on artificial media have very low levels of amylase activity, and much higher levels are found in larvae raised on maize seedlings. At pH 5.7, the optimum pH for enzyme activity, the alpha-amylases are substantially but no...
Alpha-amylase inhibitors from wheat are found noble sources to develop insect resistant transgenic plants. Thus far wheat alpha – amylase inhibitor genes have been cloned, sequenced and characterized by various researchers through cDNA library. A subunit of tetrameric alpha amylase CM3 gene was isolated and characterized directly from genomes of different Indian wheat varieties using PCR approa...
α-amylase inhibitors play a critical role in the control of diabetes and many of medicinal plants have been found to act as α-amylase inhibitors. swertia genus, belonging to the family gentianaceae, comprises different species most of which have been used in traditional medicine of several cultures as antidiabetic, anti-pyretic, analgesic, liver and gastrointestinal tonic. swertia longifolia bo...
