It has been known for a long time that the yeast Saccharomyces cerevisiae can assimilate alpha-methylglucopyranoside and isomaltose. We here report the identification of 5 genes (YGR287c, YIL172c, YJL216c, YJL221c and YOL157c), which, similar to the SUCx, MALx, or HXTx multigene families, are located in the subtelomeric regions of different chromosomes. They share high nucleotide sequence ident...
The activity of alpha-amylase, glucoamylase, maltase, trehalase, glycogen phosphorylase and trehalose phosphorylase was measured in extracts from larval and adult Hysterothylacium aduncum (Rudolphi, 1802), parasitic nematode of marine fish. The content of glycogen and trehalose in the worm's body was also determined. Both the hydrolytic and phosphorolytic paths of sugar decomposition are presen...
The significance of mucus trails derived from the herbivorous gastropods Patella caerulea, Monodonta turbinata and Tegula sp. in enhancing microbial activity in marine rocky intertidal and sublittoral zones was investigated by means of microcosm and field experiments. A pronounced increase of bacterial abundance concurrently with extracellular glucosidase activity (alpha-Dand betaD-glucosidase)...
Long-term type 2 diabetes can lead to numerous biological complications, such as hypertension and cardio-vascular disease. Key enzymes involved in the enzymatic breakdown of complex carbohydrates,pancreatic alpha-amylase and intestinal alpha-glucosidase, have been targeted as potential avenues for modulation of type 2 diabetes-associated post-prandial hyperglycemia through mild inhibition of th...
One function of N-linked glycans is to assist in the folding of glycoproteins by mediating interactions of the lectin-like chaperone proteins calnexin and calreticulin with nascent glycoproteins. These interactions can be prevented by inhibitors of the alpha-glucosidases, such as N-butyl-deoxynojirimycin (NB-DNJ) and N-nonyl-DNJ (NN-DNJ), and this causes some proteins to be misfolded and retain...
We screened seaweed species from Atlantic Canada for antidiabetic activity by testing extracts for alpha-glucosidase inhibitory effect and glucose uptake stimulatory activity. An aqueous ethanolic extract of Ascophyllum nodosum was found to be active in both assays, inhibiting rat intestinal alpha-glucosidase (IC50 = 77 microg/mL) and stimulating basal glucose uptake into 3T3-L1 adipocytes duri...
Glycogen storage disease type II (GSDII; Pompe disease), caused by inherited deficiency of acid alpha-glucosidase, is a lysosomal disorder affecting heart and skeletal muscles. A mouse model of this disease was obtained by targeted disruption of the murine acid alpha-glucosidase gene (Gaa) in embryonic stem cells. Homozygous knockout mice (Gaa -/-) lack Gaa mRNA and have a virtually complete ac...
Alpha-glucosidase inhibitory activity of fifteen Indian medicinal plants has been evaluated by in vitro enzyme assay. Methanol extracts of Cyperus rotundus (tubers), Plumbago zeylanica (root), Symplocos racemosa (bark), and Terminalia arjuna (bark) had displayed 100% inhibition with the IC50
Anti-diabetic activity of the plants may follow one or other mechanism such as their ability to restore pancreatic tissue function increase in insulin output inhibiting intestinal absorption glucose enzymes like alpha-amylase, alpha-glucosidase, etc. The alpha-amylase and alpha-glucosidase inhibition assays were performed analyze anti-diabetic potential Acacia suma. RP-HPLC method was developed...
