Abstract

The ribosomal proteins from 17 type strains of species belonging to various actinomycete genera were compared by two-dimensional polyacrylamide gel electrophoresis. I detected a striking variability among certain ribosomal proteins (designated AT-L30 proteins) with respect to electrophoretic mobility in the first dimension. In contrast, such variability was not observed among ribosomal L30 proteins from other bacteria, such as , and . Although actinomycete AT-L30 proteins from different taxa exhibited considerable heterogeneity in electrophoretic mobility, within each genus the proteins had a specific mobility characteristic. On the basis of this observation, the ribosomal AT-L30 proteins from 11 type strains of species belonging to the mycolic acid-containing genera , and were analyzed. The relative electrophoretic mobilities of AT-L30 protein preparations from these strains, as determined by two-dimensional gel electrophoresis, revealed that the genera , and can be sharply separated from each other. My results are consistent with the previously discussed view that each of these genera merits separate genus status.
