Accepted name: |
L-asparagine hydroxylase |
Reaction: |
L-asparagine + 2-oxoglutarate + O2 = (2S,3S)-3-hydroxyasparagine + succinate + CO2 |
Other name(s): |
L-asparagine 3-hydroxylase; AsnO |
Systematic name: |
L-asparagine,2-oxoglutarate:oxygen oxidoreductase (3-hydroxylating) |
Comments: |
Requires Fe2+. The enzyme is only able to hydroxylate free L-asparagine. It is not active toward D-asparagine. The β-hydroxylated asparagine produced is incorporated at position 9 of the calcium-dependent antibiotic (CDA), an 11-residue non-ribosomally synthesized acidic lipopeptide lactone. |
