EC 3.7.1.24

Accepted name: 2,4-diacetylphloroglucinol hydrolase

Reaction: 2,4-diacetylphloroglucinol + H2O = 2-acetylphloroglucinol + acetate

Glossary: phloroglucinol = benzene-1,3,5-triol
2,4-diacetylphloroglucinol = 1,1'-(2,4,6-trihydroxybenzene-1,3-diyl)diethan-1-one

Other name(s): PhlG

Systematic name: 2,4-diacetylphloroglucinol acetylhydrolase

Comments: Requires Zn2+. Isolated from the bacteria Pseudomonas fluorescens, Pseudomonas sp. YGJ3 and Mycobacterium abscessus 103. It reduces the antibiotic activity of 2,4-diacetylphloroglucinol.
