HHsearch alignment for GI: 255764481 and conserved domain: TIGR01172

>TIGR01172 cysE serine O-acetyltransferase; InterPro: IPR005881 The biosynthesis of L-cysteine is the predominant way by which inorganic sulphur is incorporated into organic compounds. In this process, the most abundant utilizable source of sulphur, inorganic sulphate, is taken up and reduced to sulphide. Sulphide is used to produce L-cysteine, which serves for protein synthesis or the production of other sulphur-containing organic compounds. Two routes for cysteine biosynthesis in nature have been documented. Serine transacetylase (2.3.1.30 from EC) catalyzes steps in pathway I, the activation of L-serine by acetyl-coenzyme A, yielding O-acetyl-L-serine.; GO: 0009001 serine O-acetyltransferase activity, 0006535 cysteine biosynthetic process from serine, 0005737 cytoplasm.
