酰胺酶

The glutamine synthetase produced by the engineering bacteria can specially act on NH4 and aminoglutaric acid, the durability to the high concentration ammonium ion has been distinctively improved because of the dissolution of adenosine acylation modification, the major bottleneck of glutamine with enzymatical production has been solved, and the concentration of the obtained glutamine can reach 47.6g/L.
