Purification, crystallization and molecular modeling of recombinant A3 lipase from an antartic Pseudomonas sp. strain AMS3
A recombinant A3 lipase from Pseudomonas sp. strain AMS 3 was previously expressed in E. coli. In present study, recombinant A3 lipase was successfully purified through Nickel-Sepharose Fast Flow affinity chromatography. This purification recovered 58.47% of yield with the purification fold 3.69. So...
