Phloroglucinol reductases (PGRs) are involved in anaerobic degradation in bacteria, in which they catalyze the dearomatization of phloroglucinol into dihydrophloroglucinol. We identified three PGRs, from different bacterial species, that are members of the family of NAD(P)H‐dependent short‐chaindehydrogenases/reductases (SDRs). In addition to catalyzing the reduction of the physiological substrate
Two naturally occurring rare 5-oxo beta-triketones, AB5046A and AB5046B, were efficiently synthesized in five linear steps with overall yields of 36% and 28%, respectively. The synthetic strategy highlighted the readily preparation of the key intermediate, 3-ethoxy-5-hydroxycyclohex-2-enone, from commercially available phloroglucinol. (C) 2018 Elsevier Ltd.

The invention provides cells and related methods for the biosynthetic production of phloroglucinol and its derivatives. The phloroglucinol can accumulate in the medium at increased concentrations without substantially inducing end product inhibition. For example, the phloroglucinol product can accumulate to a concentration above about 5 g/L in the medium without substantially inducing product inhibition. The invention includes recombinant cells that have resistance to phloroglucinol toxicity and that are transformed to biologically synthesize phloroglucinol. The invention also includes methods for selecting and transforming such cells. Furthermore, the invention includes recombinant cells having a phloroglucinol reductase that mitigates end product inhibition by the phloroglucinol and facilitates the accumulation of phloroglucinol and its derivatives.

The invention provides nucleic acids, amino acids, cells, and related methods for the biosynthetic production of dihydrophloroglucinol. In various embodiments, the invention includes an isolated or recombinant phloroglucinol reductase, which can be used in conjunction with an enzyme system for the biosynthetic production of phloroglucinol. The synthesis can be from a renewable carbon source. The dihydrophloroglucinol can be used in subsequent reactions, or can be converted into phloroglucinol that can be used in subsequent reactions.
