The small transcriptional repressor CopG protein (45 amino acids) encoded by the streptococcal plasmid pMV158 was purified to near homogeneity. Gel filtration chromatography and analytical ultracentrifugation showed that the native protein is a spherical dimer of identical subunits. Circular dichroi
