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]

Uses

in-vitro membrane-impermeant G/C-specific fluorescent DNA-binding dye.^[3]
in-vitro antibiotic of gram-positive bacteria, through inhibition of the incorporation of P_i in the RNA.^[1]
in-vitro anticancer drug that inhibits RNA synthesis.^[5]
Evaluation of male fertility: Chromomycin A₃ and protamines compete for the same binding sites in the DNA, so CMA₃ positivity in spermatozoa reflects protamine deficiency (affecting sperm morphology and decreasing fertility).^[6]^[7]
