The role of papain in the association process of a 1-pyrenoyl pendant attached to its active site was written by Sakurai, Tadamitsu;Watanabe, Kenichiro;Nojima, Kazue;Inoue, Hiroyasu. And the article was included in Journal of the Chemical Society, Chemical Communications in 1995.SDS of cas: 80480-15-5 The following contents are mentioned in the article:
An anal. of the spectroscopic behavior of papain modified by 1-bromoacetylpyrene demonstrates that the active site of this enzyme remarkably promotes the formation of the ground-state dimer derived from the pyrenoyl pendant covalently bound to the cysteine-25 residue. This study involved multiple reactions and reactants, such as 2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5SDS of cas: 80480-15-5).
2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5) belongs to organobromine compounds. Organo bromine compounds are versatile compounds and are widely used in diverse fields. Organo bromine derivatives are used in the dye sector, as an indicator in analytical chemistry (Bromothymol blue is a popular indicator). Bromine-containing agents predominate because not only are they more efficient than similar chlorine-containing species, but also the high atomic weight of bromine ensures that it is present in a high mass fraction within most organobromine compounds.SDS of cas: 80480-15-5
