More Information
Summary:The present invention relates to a microorganism genetically modified for the production of serine and/or cysteine, wherein said microorganism comprises the expression of a heterologous gapN gene coding an NADP-dependent glyceraldehyde-3-phosphate dehydrogenase, and the attenuation of the expression of the gapA gene and of the expression of sdaA and/or sdaB gene(s) as compared to an unmodified microorganism. The present invention also relates to a method for the production of serine and/or cysteine using said microorganism.
