RESUMO

This is a report on the analysis of genes involved in translation of the complete genomes of Mycoplasma hyopneumoniae strain J and 7448 and Mycoplasma synoviae. In both genomes 31 ORFs encoding large ribosomal subunit proteins and 19 ORFs encoding small ribosomal subunit proteins were found. Ten ribosomal protein gene clusters encoding 42 ribosomal proteins were found in M. synoviae, while 8 clusters encoding 39 ribosomal proteins were found in both M. hyopneumoniae strains. The L33 gene of the M. hyopneumoniae strain 7448 presented two copies in different locations. The genes encoding initiation factors (IF-1, IF-2 and IF-3), elongation factors (EF-G, EF-Tu, EF-Ts and EF-P), and the genes encoding the ribosome recycling factor (frr) and one polypeptide release factor (prfA) were present in the genomes of M. hyopneumoniae and M. synoviae. Nineteen aminoacyl-tRNA synthases had been previously identified in both mycoplasmas. In the two strains of M. hyopneumoniae, J and 7448, only one set of 5S, 16S and 23S rRNAs had been identified. Two sets of 16S and 23S rRNA genes and three sets of 5S rRNA genes had been identified in the M. synoviae genome.
