Investigation of mosA, a protein implicated in rhizopine biosynthesis
MosA is a protein found in Sinorhizobium meliloti L5-30 and has been suggested to be responsible for the biosynthesis of the rhizopine 3-O-methyl-scyllo-inosamine (3-MSI) from scyllo-inosamine (SI). However, we have shown MosA is a dihydrodipicolinate synthase (DHDPS) catalyzing the condensation of …
