Thermally responsive polymers and their applications
… of polymeric materials that can alter their functions according to temperature changes. We chose poly(N-isopropylacrylamide) (polyNIPA) as a platform, which phase-separates from water upon heating. The thermally responsive properties and applications of polyNIPA are introduced in Chapter One. In …

Copper tolerance of Listeria monocytogenes strain DRDC8.
… factors required for effective colonisation and infection of mammalian hosts have been well described, other genes may modulate disease persistence. For L. monocytogenes strain DRDC8, the ctpA gene encodes a copper transporting P-type ATPase that apparently maintains intra-cellular copper …

Engineering the interface of cytochrome b5 and myoglobin for in vitro and in vivo applications
Heme-copper oxidases (HCOs) are large membrane proteins found in both bacteria and in eukaryotes. They catalyze about 90% of oxygen reduction in the atmosphere. They utilize a heme-copper center, which is comprised of a heme and a copper ion coordinated with three histidines, to catalyze the …

Metalloprotein engineering with unnatural amino acids: application in functional heme-copper oxidase and azurin
Metalloproteins, proteins with metal ion cofactors, are estimated to make up more than a third of total proteome. They involve in key biological processes such as photosynthesis, respiration, and nitrogen fixation. The important roles and potential applications of metalloprotein urges the need for …

Two Methodologies in Pursuit of the Elucidation of Copper (II)—Centered Bioinorganic Chemistry
Copper is a widely distributed transition metal in the earth's crust and has been adopted in a variety of biological systems. In many ways the biochemical usefulness of copper stems from its positive redox potential. This positive redox potential allows copper to assist in the movement of …
