Phoa induction
Webb1 jan. 1999 · This permitted a Tn phoA -specific primer to be used to determine the sequence of the Agrobacterium DNA adjacent to the transposon in each plasmid. Of the sequences obtained, only those from LTU61 (in pVS1501) and LTU62 (in pVS1502) shared homology with known genes (see below). Webb1 okt. 2006 · Summary To examine the relationship between folding and aggregation in the periplasm of Escherichia coli, we have analysed the cellular fates of exported proteins fused to either the wild‐type maltose‐binding protein (MalE) or the aggregation‐prone variant MalE31. The propensity of fusion proteins to aggregate in the periplasm was …
