Polyester compound

The present invention provides a method for conveniently and efficiently producing a 3-acetylamino-4-hydroxybenzoic acid-type compound that is a stable compound by a process using a microorganism. Specifically the present invention provides a microorganism having an ability to produce 3-amino-4-hydroxybenzoic acid, that is modified so as to increase an activity to form 3-amino-4-hydroxybenzoic acid from dihydroxyacetone phosphate and aspartate semialdehyde, wherein the microorganism is modified so as to increase an N-hydroxyarylamine O-acetyltransferase (NhoA) activity, as well as a method for producing the 3-acetylamino-4-hydroxybenzoic acid-type compound using such a microorganism.
