S-adenosylmethionine (SAM), an important metabolite in all living organisms, has been widely used to treat various diseases. To develop a simple and efficient method to produce SAM, an engineered variant of the methionine adenosyltransferase (MAT) from Escherichia coli was investigated for its potential use in the enzymatic synthesis of SAM due to its significantly decreased product inhibition....

While dismantling nuclear power plants, the reactor vessel internal is cut underwater using mechanical and thermal cutting. In laser cutting, assist gas must be used to remove melted metal; consequently, a large number of radioactive aerosols can generated. To reduce generation aerosols, pressure should lowered. However, below limit, molten metal not well-removed from surface fails cut. this st...
