The discovery of the metal salen-catalyzed asymmetric ring-opening (ARO) of epoxides is chronicled. A screening approach was adopted for the identification of catalysts for the addition of TMSN(3) to meso-epoxides, and the chiral (salen)CrN(3) complex was identified as optimal. Kinetic

Somatic cell-embryo coculture enhances embryo development in vitro by producing embryotrophic factor(s) and/or removing harmful substances from the culture environment. Yet, the underlying molecular mechanisms on how somatic cells remove the toxicants from the culture medium remain largely unknown. By

Regulation of angiogenesis is critical for many diseases. Specifically, pathological retinal neovascularization, a major cause of blindness, is suppressed with dietary ω3-long-chain polyunsaturated fatty acids (ω3LCPUFAs) through antiangiogenic metabolites of cyclooxygenase and lipoxygenase. Cytochrome P450 epoxygenases (CYP2C8) also metabolize LCPUFAs

Questions

  1. Hello, I was wondering if you could please let me know the molecular weight of this enzyme from Rhodococcus rhodochrous.

    1 answer
    1. The molecular weight of this product has not been determined. Various publications suggest that this enzyme is a dimer with an approximate molecular weight of 110,000 daltons. Each subunit is reported to be 57,000 daltons. See the link below for additional information:
