This domain is found in 2,4-diacetylphloroglucinol hydrolase PhiG present in Pseudomonas fluorescens. 2,4-diacetylphloroglucinol hydrolase is the gene product of PhiG that is responsible for cleaving toxic 2,4-diacetylphloroglucinol (DAPG). The small N-terminal region of the domain is involved in dimerization through hydrogen bonding of the dimer interface. The C-terminal catalytic region resembles the tetracenomycin aromatase/cyclase and has a Bet v1-like fold. DAPG PhiG is the first discovered hydrolase whose catalytic domain belongs to the Bet v1-like fold, rather than the classical alpha/beta-fold hydrolases [1].
