Potential anti-hyperglycemic activity of black tea theaflavins through inhibiting α-amylase

Food Chemistry: X
Hyperglycemia can cause early damage to human bady and develop into diabates that will severely threaten human healthy. The effectively clinical treatment of hyperglycemiais is by inhibiting the activity of α-amylase.

Biochemical characterization of α-amylase from the yeastCryptococcus flavus [PDF]

FEMS Microbiology Letters, 2004
During our screening of amylolytic microorganisms from Brazilian fruits, we isolated a yeast strain classified as Cryptococcus flavus. When grown on starch-containing medium this strain exhibited the highest amylase production after 24 h of cultivation. The extracellular amylase from C.

Discriminator‐Guided Inverse Folding for Multi‐Property Protein Design

Advanced Science, EarlyView.
Discriminator‐Guided Inverse Folding (DGIF) integrates multiple property predictors trained from single‐property datasets to guide protein sequence generation from a backbone structure. DGIF enables simultaneous improvement of thermostability and solubility without requiring multi‐property annotated datasets and generates designs that move toward the ...

Cloning of a thermostable α-amylase gene fromBacillus licheniformisand its expression inEscherichia coliandBacillus subtilis [PDF]

FEMS Microbiology Letters, 1984
The gene coding for the thermostable α-amylase Bacillus licheniformis has been isolated from a direct shotgun in Escherichia coli using the bacteriophage lambda as a vector. The fragment containing the α-amylase gene has been sub-cloned in pBR322 and its restriction map determined. The α-amylase produced by the E.

Protease‐Triggered Chromogenic Release From Peptide‐Modified Calcium Carbonate Microspheres Enables Colorimetric Detection of Porphyromonas gingivalis Activity

Advanced Science, EarlyView.
We report a chromogenic release‐based assay system with protease‐cleavage peptide‐modified calcium carbonate microspheres for colorimetric detection of Porphyromonas (P.) gingivalis activity. In response to Arg‐specific gingipain secreted by P. gingivalis, the supernatant becomes colored, enabling colorimetric analysis and providing the monitoring of ...

Production and biochemical characterization of an α-amylase from the moderate halophileHalomonas meridiana [PDF]

FEMS Microbiology Letters, 2000
Extracellular amylase production by the moderate halophile Halomonas meridiana was optimized and the enzyme was characterized biochemically. The highest amylase production was achieved by growing H. meridiana cultures in media with 5% salts and starch, in the absence of glucose until the end of the exponential phase.
