Trimethylpyrrocorphin
WebMar 1, 2006 · A minor absorption peak at 375 nm and major one at 350 nm were recorded in the range of 300–700 nm (Fig. 1B), which is the specific peak of sirohydrochrolin and trimethylpyrrocorphin, respectively [9]. WebThe cobA gene codes for uroporphyrinogen III methyltransferase that converts the substrate uroporphyrinogen (urogen) III into two fluorescent compounds sirohydrochlorin and trimethylpyrrocorphin. Urogen III is ubiquitous within the cell, however, because the cells use it for vitamin B 12 and siroheme biosynthesis, this sensing system is limited by substrate …
