General description
4-Nitrophenyl trimethylacetate undergoes hydrolysis catalysed by cytoplasmic aldehyde dehydrogenase in presence of NAD+, NADH, propionaldehyde, chloral hydrate, diethylstilboestrol and p-nitrobenzaldehyde (modifiers).
Application
4-Nitrophenyl trimethylacetate was used as sensitive probe to study the catalytic activity of carboxypeptidase Y.

The effects of modifiers (NAD+, NADH, propionaldehyde, chloral hydrate, diethylstilboestrol and p-nitrobenzaldehyde) on the hydrolysis of p-nitrophenyl (PNP) pivalate (PNP trimethylacetate) catalysed by cytoplasmic aldehyde dehydrogenase are reported. In each case a different inhibition pattern is obtained to that observed
