Reaction: 2 2-acetylphloroglucinol = 2,4-diacetylphloroglucinol + phloroglucinol
Glossary: phloroglucinol = benzene-1,3,5-triol
Other name(s): MAPG ATase
Systematic name: 2-acetylphloroglucinol C-acetyltransferase
Comments: The enzyme from the bacterium Pseudomonas sp YGJ3 is composed of three subunits named PhlA, PhlB and PhlC. Production of 2,4-diacetylphloroglucinol, which has antibiotic activity, is strongly inhibited by chloride ions.
