Temperature is one of the most important factors for evolution. As the temperature increases, the catalytic activity of the enzyme increases correspondingly, but at the same time, the affinity between the enzyme and the substrate decreases. It has been proved that metal ions enhance the activity, stability and substrate affinity of metal enzymes. However, the role of metal ions-binding amino acids in thermophilic adaptation is not clear. Recently, a research team led by Prof. LI Fuli from Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS), unraveled the function of metal ions-binding amino acids in improving substrate affinity. Temperature is one of the most important factors for evolution. As the temperature increases, the catalytic activity of the enzyme increases correspondingly, but at the same time, the affinity between the enzyme and the substrate decreases. It ha...

As regards the demand for energy storage batteries, higher energy density and safer property has been the imperative target with the rapid market expansion of electric vehicles and grid-scale storage systems. Among various new battery technologies, rechargeable Mg battery has attracted increasing attention from researchers. Mg anode inherently possesses incomparable superiorities which are high safety, high volumetric capacity, earth-abundant element (the fifth most abundant in the earth crust) and low cost (about 30 times cheaper than Li). Nevertheless, the lack of compatible electrolytes and suitable cathodes has restricted the further development of rechargeable Mg battery. As regards the demand for energy storage batteries, higher energy density and safer property have been the imperative target with the rapid market expansion of electric vehicles and grid-scale storage systems. Among various new battery technologie...
