IUBMB Enzyme Nomenclature


Accepted name: acetylspermidine deacetylase

Reaction: N8-acetylspermidine + H2O = acetate + spermidine

Glossary: spermidine

Other name(s): N8-monoacetylspermidine deacetylase; N8-acetylspermidine deacetylase; N-acetylspermidine deacetylase; N1-acetylspermidine amidohydrolase (incorrect)

Systematic name: N8-acetylspermidine amidohydrolase

Comments: It was initially thought that N1-acetylspermidine was the substrate for this deacetylase reaction [1] but this has since been disproved by Marchant et al. [3].
