EC 2.3.1.246     
Accepted name: 3,5-dihydroxyphenylacetyl-CoA synthase
Reaction: 4 malonyl-CoA = (3,5-dihydroxyphenylacetyl)-CoA + 3 CoA + 4 CO2 + H2O
Other name(s): DpgA
Systematic name: malonyl-CoA:malonyl-CoA malonyltransferase (3,5-dihydroxyphenylacetyl-CoA-forming)
Comments: The enzyme, characterized from the bacterium Amycolatopsis mediterranei, is involved in biosynthesis of the nonproteinogenic amino acid (S)-3,5-dihydroxyphenylglycine, a component of the vancomycin-type antibiotic balhimycin.
