pNP-Assay
About
pNP-assays are a common way to quantify hydrolytic activity. We use para-Nitrophenylbutyrate (pNPB) as a substrate. As the catalysts we use the enzymes[http://partsregistry.org/wiki/index.php?title=Part:BBa_K808025 FsC], [http://partsregistry.org/wiki/index.php?title=Part:BBa_K808026 pNB-Est13] or our transformed and induced bacteria.
Conditions: T = 34°C pH = 7.4
Method: Measurement of absorption at 405nm every minute over 30 minutes, after addition of enzyme
