Biological Activity
The CBR3 protein uses NADPH to convert carbonyl compounds into alcohols. CBR3 Protein, Human (His) is the recombinant human-derived CBR3 protein, expressed by E. coli , with N-His labeled tag.
CBR3, a multifaceted enzyme, catalyzes the NADPH-dependent reduction of various carbonyl compounds, transforming them into their respective alcohols. Although it exhibits low NADPH-dependent oxidoreductase activity, CBR3 is particularly effective on orthoquinones, including 1,2-naphthoquinone, showcasing its potential role in protecting against the cytotoxic effects of exogenous quinones. The enzyme is not limited to quinones, as it also acts on non-quinone compounds like isatin and the anticancer drug oracin. CBR3's preference for ortho-quinones over paraquinones highlights its substrate specificity. Notably, no endogenous substrate, aside from isatin, has been identified for CBR3, underscoring its versatility and potential contributions to cellular detoxification processes.
The enzyme activity of this recombinant protein is testing in progress, we cannot offer a guarantee yet.
