Beschreibung
Zusammenfassung:	The present disclosure relates to ß-class carbonic anhydrase polypeptides having improved properties including increased thermostability and/or stability in the presence of amine compounds, ammonia, or carbonate ion. The present disclosure also provides formulations and uses of the polypeptides for accelerating the absorption of carbon dioxide from a gas stream into a solution as well as for the release of the absorbed carbon dioxide for further treatment and/or sequestering. Also provided are polynucleotides encoding the carbonic anhydrase polypeptides and host cells capable of expressing them. La présente invention concerne des polypeptides d'anhydrase carbonique de classe ß ayant des propriétés améliorées, y compris une plus grande thermostabilité et/ou stabilité en présence de composés amine, d'ammoniac, ou d'un ion carbonate. La présente invention concerne également des formulations et des utilisations des polypeptides pour accélérer l'absorption de dioxyde de carbone d'un courant de gaz dans une solution ainsi que pour libérer du dioxyde de carbone pour un traitement et/ou une séquestration ultérieurs. La présente invention concerne en outre des polynucléotides codant pour les polypeptides d'anhydrase carbonique et des cellules hôtes capables de les exprimer.
