The heat-resistant carbonic anhydrase mutant can be applied to a high-temperature carbon dioxide capture process due to high stability at high temperatures and a high carbon dioxide hydration rate.

Methods, compositions, and treatment protocols for treating ischemic wounds and inflammatory conditions in a patient. The treatment protocols comprise or consist of using a modified collagen gel (MCG) to promote healing of ischemic wounds and reduce inflammation at the wound site and in other inflammatory conditions. The modified collagen gel comprises generally a dispersion of collagens in an aqueous matrix comprising water and glycerine, where the amount of Type I collagen is greater than the amount of Type II and Type III collagens in the gel.

A dissolved CO.sub.2 change in aqueous solutions affects directly the intracellular pH (pHi) value as it does so by influencing therefore important cellular processes. The enzyme carbonic anhydrase II (CAII) catalyzes the equilibrium of CO.sub.2 in aqueous solutions and because it alters the speed at which this equilibrium is reached it was identified as a strong candidate for metabolic engineering. The cell line stably expressing hCAII presented a better initial re-alkalinization of cytoplasm after induced CO.sub.2 acid load. The most alkaline pHi value associated to the lowest pHi variations was observed for that cell line in long term increased CO.sub.2 levels. In general, the increased CO.sub.2 profile triggered the quicker progress of G0G1-cell cycle phase for both transfected and control cell lines.
