Transfer RNAs of Mycoplasma capricolum were separated by two-dimensional polyacrylamide gel electrophoresis, and the relative abundance of each of the 28 known tRNA species was measured. There existed a correlation between the relative amount of isoacceptor tRNAs and the frequency in choosing synonymous codons that could be translated by the isoacceptors. Furthermore, it was observed that the t...

www.sciencemag.org SCIENCE VOL 329 2 JULY 2010 5 COVER Electron micrograph of Mycoplasma mycoides JCVI-syn1.0 cells (magnifi cation ~25,000×). These cells were produced following transplantation of a 1.08–megabase pair synthetic M. mycoides genome into M. capricolum recipient cells. The cells are controlled by the synthetic genome, exhibit the expected phenotypic properties, and are capable of ...

Sterol synergism as previously observed [Dahl, C.E., Dahl, J.S. & Bloch, K. (1980) Biochemistry 19, 1462-1467] and defined as a greater-than-additive growth response to pairs of sterols by Mycoplasma capricolum [Dahl, J.S., Dahl, C.E. & Bloch, K. (1981) J. Biol. Chem. 256, 87-91] is now demonstrated in the yeast mutant GL7, which is auxotrophic for sterol and unsaturated fatty acid. Mutant cell...

Contagious caprine pleuropneumonia (CCPP) is caused by Mycoplasma capricolum subsp. capripneumoniae (Mccp) which belongs to the Mycoplasma mycoides cluster, a group of five closely related Mycoplasmas, pathogenic to ruminants. The true lesions of CCPP are restricted to the alveolar tissues of infected goats, which distinguish it from other respiratory diseases of small ruminants caused by membe...
