Dissolution of Candida antarctica lipase B in ionic liquids: effects on structure and activity
Abstract
The effects of ionic liquid media on the activity of Candida antarctica lipase B in a simple transesterification reaction were studied. In ionic liquids containing alkylsulfate, nitrate and lactate anions, which dissolved CaLB, the reaction was at least ten times slower than in [BMIm][BF4]. Only [Et3MeN][MeSO4] was an exception, as dissolved CaLB maintained its activity in this solvent. By means of FT-IR spectroscopy, denaturation of CaLB was observed upon dissolution in ionic liquids in which the activity was low, whereas the conformation of enzyme dissolved in [Et3MeN][MeSO4] closely resembled the native one.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
