Protein
2-hydroxyethylphosphonate dioxygenase
Organism
Streptomyces viridochromogenes (strain DSM 40736 / JCM 4977 / BCRC 1201 / Tue 494)
Function
Non-heme-dependent dioxygenase that catalyzes the conversion of 2-hydroxyethylphosphonate (HEP) to hydroxymethylphosphonate (HMP) in the biosynthesis of phosphinothricin tripeptide (PTT). PTT contains the unusual amino acid phosphinothricin attached to 2 alanine residues. Synthetic phosphinothricin (glufosinate) is a key component of commercial herbicides.
Similarity
Belongs to the non-heme iron-dependent dioxygenase family.
