Summary: | The present invention provides methods for the production of cysteine or derivates thereof by culturing a microorganism having reduced activity of endogenous phosphoserine phosphatase. The O-phosphoserine produced by such an organism can then be reacted with a sulfide in the presence of a sulfydrylase or a microorganism expressing a sulfhydrylase to produce cysteine or a derivative thereof. Microorganisms having the properties noted above are also provided herein. |
