摘要

Preparing 2-amino-1,3-propanediol (serinol) starting from a substrate containing glycerol, comprises converting glycerol by a dihydroxyacetone-phosphate aminotransferase/dihydro rhizobitoxin synthase (RtxA), or its portion, preferably a portion, which has at least the first 513 amino acids on the N-terminus of the enzymes. An independent claim is included for an expression strain and/or a microorganism, which contains rtxA gene and/or its portion, preferably at least a portion, which is coded for RtxA513.
