== Function ==
[https://www.uniprot.org/uniprot/FRBJ_STRR3 FRBJ_STRR3] Monooxygenase involved in the biosynthesis of the phosphonate antibiotic FR-33289, an antimalarial agent (PubMed:20142041). Catalyzes the oxidative decarboxylation of the antibiotic FR-900098 (3-(N-acetyl-N-hydroxy)aminopropylphosphonate) to form FR-33289 ((R)-(3-(acetylhydroxyamino)-2-hydroxypropyl)phosphonate) (PubMed:20142041).<ref>PMID:20142041</ref>

== Publication Abstract from PubMed ==
FrbJ is a member of the Fe(2+)/alpha-ketoglutarate-dependent dioxygenase family which hydroxylates the natural product FR-900098 of Streptomyces rubellomurinus, yielding the phosphonate antibiotic FR-33289. Here, the crystal structure of FrbJ, which shows structural homology to taurine dioxygenase (TauD), a key member of the same family, is reported. Unlike other members of the family, FrbJ has an unusual lid structure which consists of two beta-strands with a long loop between them. To investigate the role of this lid motif, a molecular-dynamics simulation was performed with the FrbJ structure. The molecular-dynamics simulation analysis implies that the lid-loop region is highly flexible, which is consistent with the fact that FrbJ has a relatively broad spectrum of substrates with different lengths. Interestingly, an access tunnel is found at the back of the active site which connects the putative binding site of alpha-ketoglutarate to the solvent outside.
