L-asparagine,2-oxoglutarate:oxygen oxidoreductase (3-hydroxylating)

Requires Fe2+. The enzyme is only able to hydroxylate free L-asparagine. It is not active toward D-asparagine. The beta-hydroxylated asparagine produced is incorporated at position 9 of the calcium-dependent antibiotic (CDA), an 11-residue non-ribosomally synthesized acidic lipopeptide lactone.
