Abstract
The present invention relates to a method for producing cysteine or derivatives thereof using novel O-phosphoserine sulfhydrylase. According to the present invention, a method for producing cysteine by novel O-phosphoserine sulfhydrylase (OPSS) using O-phosphoserine as a substrate is provided, and this method is advantageous in that cysteine can be simply and environmental-friendly produced in a high yield.
Claims6
A method for producing cysteine or derivatives thereof, comprising the step of reacting O-phosphoserine (OPS) with a sulfide in the presence of O-phosphoserine sulfhydrylase (OPSS) having an amino acid sequence represented by SEQ ID NO:
- 1 or 2, or a microorganism expressing the same, thereby producing cysteine or the derivatives thereof, wherein said method further comprises the step of separating and purifying the cysteine or derivatives thereof.
