IUBMB Enzyme Nomenclature


Accepted name: 2'-N-acetylparomamine deacetylase

Reaction: 2'-N-acetylparomamine + H2O = paromamine + acetate

Glossary: paromamine = (1R)-O4-(2-amino-2-deoxy-α-D-glucopyranosyl)-2-deoxy-streptamine

Other name(s): btrD (gene name); neoL (gene name); kanN (gene name)

Systematic name: 2'-N-acetylparomamine hydrolase (acetate-forming)

Comments: Involved in the biosynthetic pathways of several clinically important aminocyclitol antibiotics, including kanamycin, butirosin, neomycin and ribostamycin. The enzyme from the bacterium Streptomyces fradiae can also accept 2'''-acetyl-6'''-hydroxyneomycin C as substrate, cf. EC, 2'''-acetyl-6'''-hydroxyneomycin C deacetylase [2].
