Polyacrylamide gel electrophoresis analysis of ribosomal protein AT-L30 as a novel approach to actinomycete taxonomy: application to the genera Actinomadura and Microtetraspora.

Actinomycete ribosomal protein AT-L30 exhibits electrophoretic mobility that is specific for each genus. On the basis of this fact, we analyzed ribosomal AT-L30 proteins from 26 type strains of species belonging to the genera Actinomadura and Microtetraspora. The electrophoretic mobilities of AT-L30 preparations from these strains, as determined by two-dimensional polyacrylamide gel electrophoresis, revealed that they could be divided into two groups, one group with relative electrophoretic mobilities of 14.0 to 41.5 and another group with relative electrophoretic mobilities of -6.5 to 0. The first group corresponded to the genus Actinomadura, and the second group corresponded to the genus Microtetraspora. Partial amino acid sequencing of AT-L30 preparations from several strains proved that we were indeed dealing with the specified protein homologous to ribosomal protein L30 of Escherichia coli. Our results strongly supported the conclusions of previous work and thus proved the efficacy of ribosomal protein analysis as a novel approach for taxonomy of actinomycetes.[1]
