Research ArticleOpen accessPhrase in the titleDESIGN OF CANDIDA ANTARCTICA LIPASE B THERMOSTABILITY IMPROVEMENT BY INTRODUCING EXTRA DISULFIDE BOND INTO THE ENZYMEUsman Sumo Friend Tambunan, Ahmad Randy, Arli Aditya ParikesitCandida Antarctica Lipase B (CALB) is extensively studied in enzymatic production of biodiesel, pharmaceutical products, detergents and other chemicals. One drawback of using CALB is its relatively low optimum temperature at 313 K (40°C). The objective of this research is to design CALB mutant with improved thermostability by introducing extra disulfide bond. Molecular dynamic simulation was conducted to get better … …OnLine Journal of Biological Sciences, Vol. 14, Issue 2 · 18 Apr 2014 · 9,492 accessesView PDF Cite

Research ArticleOpen accessIn the abstractLIPASE-CATALYZED TRANSESTERIFICATION OF PALM KERNEL OIL WITH DIALKYLCARBONATESTjahjono Herawan, M. Rüsch Gen. KlaasLipase-catalyzed transesterifications-especially in a solvent-free medium-are important for industrial applications because such systems would have an enormous advantage by avoiding the problem of separation, toxicity and flammability of organic solvents. However, the organic solvent-free alcoholysis, especially methanolysis, does not give high conversions. The same problem also occurs when ethyl or methyl acetate are used as acyl acceptors. The main problems … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 6 May 2014 · 6,793 accessesView PDF Cite
