Purification and characterization of a hyperthermostable and high maltogenic alpha-amylase of an extreme thermophile Geobacillus thermoleovorans.
Uma Maheswar Rao JL, Satyanarayana T. Uma Maheswar Rao JL, et al. Appl Biochem Biotechnol. 2007 Aug;142(2):179-93. doi: 10.1007/s12010-007-0017-4. Appl Biochem Biotechnol. 2007. PMID: 18025579
Among different additives and detergents, polyethylene glycol 8000 and Tween 20, 40, and 80 stabilized the enzyme activity, whereas Triton X-100, glycerol, glycine, dextrin, and sodium dodecyl sulfate inhibited to a varied extent. alpha-Amylase exhibited activity on several starc …

Biophysical and biochemical characterization of a hyperthermostable and Ca2+ -independent alpha-Amylase of an extreme thermophile Geobacillus thermoleovorans.
Uma Maheswar Rao JL, Satyanarayana T. Uma Maheswar Rao JL, et al. Appl Biochem Biotechnol. 2008 Aug;150(2):205-19. doi: 10.1007/s12010-008-8171-x. Epub 2008 Apr 29. Appl Biochem Biotechnol. 2008. PMID: 18443744
The circular dichroism spectroscopic data revealed the native alpha-amylase gt to contain 25% alpha-helix, 21% beta-sheet, and 54% random coils. The addition of urea, at high concentration (8 M), appeared to expose the buried Trp residues of the native alpha-amylase gt to …
