What about those hydrolases ?

Figure.1 Enzyme substrate reaction of the hydrolases and respective substrates

We use hydrolases to realize a colorimetric response by conversion of a specific substrate. We will use five hydrolases : Beta-Galactosidase (lacZ),Beta-Glucuronidase (GusA); alkaline phosphatase (phoA);Glycoside hydrolase (NagZ) and the acetyl esterase (aes).

On this page you will find all relevant information on the hydrolases and enzyme substrate reactions based on papers and our results.
