摘要: Provided is a microorganism that is capable of efficiently producing para-aminobenzoic acid (4-ABA) or a salt thereof, using saccharides as raw materials, and a method for efficiently producing 4-ABA or a salt thereof by using this microorganism.
A transformant obtained by introducing, into a coryneform bacterium, a gene that encodes 4-amino-4-deoxychorismate lyase, a gene that encodes a para-aminobenzoate synthase component I, and a gene that encodes a para-aminobenzoate synthase component II, is capable of efficiently producing 4-ABA or a salt thereof from saccharides.-

摘要: Provided is a microorganism that is able to efficiently produce protocatechuic acid or a salt thereof by using a saccharide as a raw material, and a method of efficiently producing protocatechuic acid or a salt thereof by using the microorganism. Provided is a transformant having protocatechuic acid producing ability, subjected to modifications of enhancement of 3-dehydroshikimate dehydratase activity; enhancement of chorismate pyruvate lyase activity; and enhancement of 4-hydroxybenzoate hydroxylase activity. Also provided is a method of producing protocatechuic acid or a salt thereof, including the step of culturing the transformant in a reaction solution containing a saccharide so as to cause the transformant to produce protocatechuic acid or a salt thereof.

摘要: An objective of the present invention is to provide a microorganism capable of efficiently producing aniline from aminobenzoic acid, and a process for efficiently producing aniline from aminobenzoic acid. To achieve the objective, provided is an aniline-producing transformant constructed by introducing a gene which encodes an enzyme having aminobenzoate decarboxylase activity into a coryneform bacterium as a host, characterized in that the enzyme having aminobenzoate decarboxylase activity is composed of an amino acid sequence which is the same as that represented by SEQ ID NO: 2 except for having a mutation of at least proline (P) at position 309 from the N terminus.
