Expression and functional analysis of a recombinant aquaporin Z from Antarctic Pseudomonas sp. AMS3
Abstract Aquaporin (AQP) is a water channel protein from the family of transmembrane proteins which facilitates the movement of water across the cell membrane. It is ubiquitous in nature, however the understanding of the water transport mechanism, especially for AQPs in microbes adapted to low tempe...
