Cytochrome P450 monooxygenases (CYP) are a superfamily of heme-thiolate proteins which catalyze the incorporation of oxygen atoms into substrates. Here, a self-sufficient CYP102A from Streptomyces cattleya (CYP102A_scat) was cloned, produced recombinantly in Escherichia coli strain BL21 (DE3), and the characteristic features were investigated. However, unlike other self-sufficient CYP102A enzymes...
A novel, Hg 2+ -selective chemosensor was prepared via Mannich reaction of dichlorofluorescein with piperazinyl-coumarin moiety. The dichlorofluorescein–coumarin derivative exhibited well-defined Hg 2+ -selective chromogenic behavior, indicated by a green to pink colour change in solution, as well as fluorogenic signalling. Significant changes in fluorescence of the dichlorofluorescein...
