| pubmed-article:7765824 | pubmed:abstractText | The Escherichia coli penicillin G amidase (PGA), which is a key enzyme in the production of penicillin G derivatives is generated from a precursor polypeptide by an unusual internal maturation process. We observed the accumulation of the PGA precursor polypeptide in the insoluble material recovered after sonication of recombinant E. coli JM109 cells grown at 26 degrees C. The aggregated nature of the accumulated molecules was demonstrated using detergents and chaotropic agents in solubilization assays. The periplasmic location of the aggregates was shown by trypsin-accessibility experiments performed on the spheroplast fraction. Finally, we showed that addition of sucrose or glycerol in the medium strongly reduces this periplasmic aggregation and as a consequence PGA production is substantially increased. Thus, periplasmic aggregation of the PGA precursor polypeptide limits PGA production by recombinant E. coli and this limitation can be overcome by addition in the medium of a non-metabolizable sugar, such as sucrose, or of glycerol. | lld:pubmed |
