The mitochondrial genome of Euglena gracilis.

Mitochondrial DNA from Euglena gracilis has been investigated in its chemical and physical properties. Its G + C content is equal to 25%; its buoyant density in a CsCl density gradient (1.690 g/cm3) is higher, by 5 mg/cm3, than expected for a bacterial DNA having the same base composition. The buoyant densities of denatured and renatured DNA are higher than that of native DNA by 10-12 mg/cm3 and 6 mg/cm3, respectively. The melting temperature, Tm, is 77 degrees C in standard saline citrate; the first derivative of the melting curve shows a striking multimodality. Degradation of the DNA by micrococcal nuclease indicates that about 40% of the DNA is formed by stretches lower than 10% in G + C. In all its properties the mitochondrial DNA from Euglena gracilis is strikingly similar to that of Saccharomyces cerevisiae.
