特性

Our Abpromise guarantee covers the use of ab99241 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

  • 生理活性Specific activity is > 450 nmoles/min/mg, and is defined as the amount of enzyme that cleaves 1 µmole of suc-AAFP-pNA per minute at 25°C in Tris-Hcl pH8.0 using chymotrypsin.

    Activity Assay

    1. Prepare 170 µl assay buffer into a suitable container and pre-chill on ice before use: The final concentrations are 200 mM Tris-Hcl, pH 8.0, and 20nM chymotrypsin.
    2. Add 10 µl of recombinant surA protein with 1 µg in assay buffer.
    3. Mix by inversion and equilibrate to 1°C and monitor the A405nm until the value is constant using a spectrophotometer.
    4. Add 20 µl pre-chilled 5mM suc-AAFP-pNA. (Substrate was dissolved in TFE that contained 460mM LiCl to a concentration of 3 mM)
    5. Record the increase in A405 nm for 30 minutes at 25°C.

  • 関連性surA is a chaperone involved in the correct folding and assembly of outer membrane proteins, such as ompA, ompF and lamB. It recognizes specific patterns of aromatic residues and the orientation of their side chains, which are found more frequently in integral outer membrane proteins. surA may act in both early periplasmic and late outer membrane-associated steps of protein maturation and is essential for the survival of E.coli in stationary phase.
  • 細胞内局在Periplasm. Note: Is capable of associating with the outer membrane.
