Biological activity
Biological activity: Specific activity is > 490 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
- 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.
- Add 10 µl of recombinant FKBP3 protein with 1 µg in assay buffer.
- Mix by inversion and equilibrate to 1°C and monitor the A405nm until the value is constant using a spectrophotometer.
- Add 20 µl pre-chilled 5mM suc-AAFP-pNA. (Substrate was dissolved in TFE that contained 460mM LiCl to a concentration of 3 mM)
- Record the increase in A405 nm for 30 minutes at 25°C.
