Rao JP, Grzemski W, Murphy PJ. Rao JP, et al. Microbiology (Reading). 1995 Jul;141 ( Pt 7):1683-90. doi: 10.1099/13500872-141-7-1683. Microbiology (Reading). 1995. PMID: 7551036 Free article.
This differs from the R. meliloti L5-30 mos locus, which produces 3-O-methyl-scyllo-inosamine (3-O-MSI), by the complete absence of mosA. ...Further, changes made to this ORF result in reduced levels of the rhizopine....

The MocR-like transcription factors: pyridoxal 5'-phosphate-dependent regulators of bacterial metabolism.
Tramonti A, Nardella C, di Salvo ML, Pascarella S, Contestabile R. Tramonti A, et al. FEBS J. 2018 Nov;285(21):3925-3944. doi: 10.1111/febs.14599. Epub 2018 Jul 5. FEBS J. 2018. PMID: 29974999 Free article. Review.
However, MocR-TFs are also implicated in the metabolism of compounds that are not substrates of PLP-dependent enzymes, such as rhizopine and ectoine. Genomic analyses show that MocR-TFs are widespread among eubacteria, implying an essential role in their metabolism and hig …

Structural, functional and calorimetric investigation of MosA, a dihydrodipicolinate synthase from Sinorhizobium meliloti l5-30, does not support involvement in rhizopine biosynthesis.
Phenix CP, Nienaber K, Tam PH, Delbaere LT, Palmer DR. Phenix CP, et al. Chembiochem. 2008 Jul 2;9(10):1591-602. doi: 10.1002/cbic.200700569. Chembiochem. 2008. PMID: 18536061
MosA was proposed to catalyze the conversion of scyllo-inosamine to 3-O-methyl-scyllo-inosamine (compounds known as rhizopines), despite the MosA sequence showing a strong resemblance to dihydrodipicolinate synthase (DHDPS) sequences rather than …
