Abstract
The present disclosure relates to a novel O-phosphoserine export protein, and a method for producing O-phosphoserine, cysteine, and cysteine derivatives using the same.
Claims12
A recombinant microorganism for producing O-phosphoserine in which the activity of mdtH protein is enhanced compared to its endogenous activity.
A method for producing O-phosphoserine, comprising culturing a recombinant microorganism for producing O-phosphoserine in which the activity of mdtH protein is enhanced compared to its endogenous activity, in a medium.
A method for producing cysteine or derivatives thereof, comprising:
- producing O-phosphoserine or a medium containing O-phosphoserine by culturing a recombinant microorganism for producing O-phosphoserine in which the activity of mdtH protein is enhanced compared to its endogenous activity, in a medium;
- and
- reacting the O-phosphoserine or the medium containing the same produced in Step a) with a sulfide, in the presence of O-phosphoserine sulfhydrylase (OPSS) or a microorganism containing the same.
