EC 3.5.1.112     
Accepted name: 2′-N-acetylparomamine deacetylase
Reaction: 2′-N-acetylparomamine + H2O = paromamine + acetate
For diagram of paromamine biosynthesis, click here
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 3.5.1.113, 2′′′-acetyl-6′′′-hydroxyneomycin C deacetylase [2].
