Hydrolase that specifically degrades the potent antimicrobial compound 2,4-diacetylphloroglucinol (DAPG) to equimolar amounts of mildly toxic monoacetylphloroglucinol (MAPG) and acetate. 2,4-diacetylphloroglucinol + H2O = 2-acetylphloroglucinol + acetate Expression is positively regulated by GacS and negatively regulated by RsmE. Deletion of the gene slows down but does not eliminate degradation of DAPG. Deletion does not alter the ability of the bacterium to colonise plants or promote plant growth. Belongs to the DAPG/phloretin hydrolase family.
