Degradation of Native Starch Granules by Barley alpha-Glucosidases.

Plant physiology

Sun Z, Henson CA.
PMID: 16667704
Plant Physiol. 1990 Sep;94(1):320-7. doi: 10.1104/pp.94.1.320.

The initial hydrolysis of native (unboiled) starch granules in germinating cereal kernels is considered to be due to alpha-amylases. We report that barley (Hordeum vulgare L.) seed alpha-glucosidases (EC 3.2.1.20) can hydrolyze native starch granules isolated from barley kernels...

Genetic and biochemical evidence for the involvement of alpha-1,4 glucanotransferases in amylopectin synthesis .

Plant physiology

Colleoni C, Dauvill e D, Mouille G, Bul on A, Gallant D, Bouchet B, Morell M, Samuel M, Delrue B, d'Hulst C, Bliard C, Nuzillard JM, Ball S.
PMID: 10444082
Plant Physiol. 1999 Aug;120(4):993-1004. doi: 10.1104/pp.120.4.993.

We describe a novel mutation in the Chlamydomonas reinhardtii STA11 gene, which results in significantly reduced granular starch deposition and major modifications in amylopectin structure and granule shape. This defect simultaneously leads to the accumulation of linear malto-oligosaccharides. The...

Synthesis and glycosidase inhibitory activity of new hexa-substituted C8-glycomimetics.

Beilstein journal of organic chemistry

Andriuzzi O, Gravier-Pelletier C, Bertho G, Prangé T, Le Merrer Y.
PMID: 16542023
Beilstein J Org Chem. 2005 Oct 07;1(1):12. doi: 10.1186/1860-5397-1-12.

BACKGROUND: Glycosidases are involved in several metabolic pathways and the development of inhibitors is an important challenge towards the treatment of diseases, such as diabetes, cancer and viral infections including AIDS. Thus, inhibition of intestinal alpha-glucosidases can be used...

Localization and Characterization of alpha-Glucosidase Activity in Brettanomyces lambicus.

Applied and environmental microbiology

Kumara HM, De Cort S, Verachtert H.
PMID: 16349005
Appl Environ Microbiol. 1993 Aug;59(8):2352-8. doi: 10.1128/aem.59.8.2352-2358.1993.

Brettanomyces lambicus was isolated and identified from a typical overattenuating Belgian lambic beer and exhibited extracellular and intracellular alpha-glucosidase activities. Production of the intracellular enzyme was higher than production of the extracellular enzyme, and localization studies showed that the...

Subsite affinities of beta-glucosidase from Aspergillus sojae on various xylooligosaccharides.

Journal of bioscience and bioengineering

Kimura I, Tajima S.
PMID: 16232520
J Biosci Bioeng. 1999;87(5):572-5. doi: 10.1016/s1389-1723(99)80116-9.

The subsite affinities of beta-glucosidase (EC 3.2.1.21) with high beta-xylosidase activity from Aspergillus sojae on various xylooligosaccharides (degree of polymerization: n = 2-6) were investigated by steady-state kinetic analysis. The molecular activity (k0) value of the enzyme for xylobiose...

Enzymatic synthesis of novel oligosaccharides from L-sorbose, maltose, and sucrose using kojibiose phosphorylase.

Journal of bioscience and bioengineering

Chaen H, Nishimoto T, Nakada T, Fukuda S, Kurimoto M, Tsujisaka Y.
PMID: 16233079
J Biosci Bioeng. 2001;92(2):173-6. doi: 10.1263/jbb.92.173.

Glucosyl-L-sorbose, -maltose, and -sucrose were synthesized using kojibiose phosphorylase (KPase) from Thermoanaerobacter brockii ATCC35047 with beta-D-glucose-1-phosphate (beta-G1P) as a glucosyl donor. One disaccharide and two trisaccharides thus synthesized were isolated by Toyopearl HW-40S column chromatography. The results of KPase...

d-Psicose Inhibits Intestinal alpha-Glucosidase and Suppresses the Glycemic Response after Ingestion of Carbohydrates in Rats.

Journal of clinical biochemistry and nutrition

Matsuo T, Izumori K.
PMID: 19794929
J Clin Biochem Nutr. 2009 Sep;45(2):202-6. doi: 10.3164/jcbn.09-36. Epub 2009 Aug 28.

d-psicose is one of the rare sugars present in small quantities in commercial carbohydrates and agricultural products. In this study, we investigated the effects of d-psicose on the activities of alpha-amylases and alpha-glucosidases in vitro, and evaluated the effects...

Pressure stabilization of proteins from extreme thermophiles.

Applied and environmental microbiology

Hei DJ, Clark DS.
PMID: 16349220
Appl Environ Microbiol. 1994 Mar;60(3):932-9. doi: 10.1128/aem.60.3.932-939.1994.

We describe the stabilization by pressure of enzymes, including a hydrogenase from Methanococcus jannaschii, an extremely thermophilic deep-sea methanogen. This is the first published report of proteins from thermophiles being stabilized by pressure. Inactivation studies of partially purified hydrogenases...

Acute effects of acarbose on post-prandial glucose and triglycerides in type 2 diabetics following intake of different Malaysian foods.

Asia Pacific journal of clinical nutrition

Nawawi HM, Yazid TN, Ismail F, Khalid BA.
PMID: 24394314
Asia Pac J Clin Nutr. 2000 Mar;9(1):41-5. doi: 10.1046/j.1440-6047.2000.00135.x.

Acarbose inhibits intestinal alpha-glucosidases resulting in diminished and delayed postprandial hyperglycaemia (PPH). Studies on effects of acarbose on postprandial lipaemia (PPL) have been inconclusive. Little is known about the effects of acarbose on PPH and PPL following intake of...

Alpha Glucosidase Inhibitory Activities of Plants with Focus on Common Vegetables.

Plants (Basel, Switzerland)

Type-2 diabetes mellitus is one of the most prevalent metabolic diseases in the world, and is characterized by hyperglycemia (i.e., high levels of glucose in the blood). Alpha-glucosidases are enzymes in the digestive tract that hydrolyze carbohydrates into glucose....

Prescribing Pattern of Oral Antihyperglycaemic Drugs, Rationality and Adherence to American Diabetes Association (ADA) Treatment Guidelines among Type 2 Diabetes Mellitus (T2DM) Postmenopausal Women.

Br J Hosp Med (Lond). 2013 Apr 09;74(4):182-Unknown.

As the symposium of articles in this issue shows, there are now many options for managing type 2 diabetes. Potent new oral or injectable hypoglycaemic medications can be added to older drugs or used alone. In addition to metformin,...
