3PL0 - PubMed Abstract: 
PF10014 is a novel family of 2-oxyglutarate-Fe(2+) -dependent dioxygenases that are involved in biosynthesis of antibiotics and regulation of biofilm formation, likely by catalyzing hydroxylation of free amino acids or other related ligands. The crystal structure of a PF10014 member from Methylibium petroleiphilum at 1.9 Å resolution shows strong structural similarity to cupin dioxygenases in overall fold and active site, despite very remote homology. However, one of the β-strands of the cupin catalytic core is replaced by a loop that displays conformational isomerism that likely regulates the active site.
