A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

An Escherichia coli strain containing a signal sequence mutation in the periplasmic maltose-binding protein (MBP) (malE18-1) and a point mutation in the soluble export factor SecB (secBL75Q) is completely defective in export of MBP and unable to grow on maltose (Mal- phenotype). We isolated 95 spontaneous Mal+ revertants and characterized them genetically. Three types of extragenic suppressors were identified: informational (missense) suppressors, a bypass suppressor conferring the Mal+ phenotype in the absence of MBP, and suppressors affecting the prlA gene, which encodes a component of the protein export apparatus. In this study, a novel prlA allele, designated prlA1001 and mapping in the putative second transmembrane domain of the PrlA (SecY) protein, was found. In addition, we isolated a mutation designated prlA1024 which is identical to prlA4-2, the mutation responsible for the signal sequence suppression in the prlA4 (prlA4-1 prlA4-2) double mutant (T. Sako and T. Iino, J. Bacteriol. 170:5389-5391, 1988). Comparison of the prlA1024 mutant and the prlA4 double mutant provides a possible explanation for the isolation of these prlA alleles.
