Provided is a recombinant microorganism for producing carnosine, histidine and beta-alanine and a method for producing carnosine, histidine and beta-alanine by using same and, more particularly, to: a recombinant microorganism for high production of carnosine, histidine and beta-alanine produced through the redesign of metabolic pathways; a method for producing same; and a method for producing carnosine, histidine and beta-alanine by using same. According to the present invention, in a microorganism capable of producing histidine and beta-alanine, by enhancing the pentose phosphate pathways through the replacement of a pentose phosphate pathway-related operon gene with a highly expressing synthetic promoter and the replacement of a pgi gene with an initiation codon, and inducing enhancement of the production of histidine and beta-alanine through the overexpression of genes on histidine and beta-alanine metabolic pathways, respectively, it is possible to develop a recombinant microorganism for high production of histidine and beta-alanine.

The present disclosure provides compositions and methods for the biosynthetic production of carnosine and beta-alanine.
