Nuclear receptors are transcription factors that are essential in embryonic development, cellular differentiation, metabolism. Ligand-regulated nuclear PXR receptor responds to diverse arrays of chemically distinct ligands, xenobiotics, drugs and regulates expression of the genes involved in xenobiotic and drug...
In the well-characterised propanediol utilisation BMC, a vitamin B12 dependent lyase enzyme acts on the 1,2-propanediol substrate to produce propionaldehyde10; while the lyase in the ethanolamine utilisa- tion BMC produces acetaldehyde and ammonia as its products16. A recently discovered family of ...
