Chemical compound
Chromomycin A3 (CMA3 ) or Toyomycin is an anthraquinone antibiotic glycoside produced by the fermentation of a certain strain of Streptomyces griseus (No. 7).[ 1]
Fluorescence properties
In the presence of Mg2+ ions , Chromomycin A3 binds reversibly to DNA , preferentially to contiguous G /C base pairs .[ 2] [ 3]
When bound to DNA, Chromomycin A3 has a maximum excitation wavelength of 445 nm (blue ), and a maximum emission wavelength of 575 nm (yellow ).[ 4]
