Abstract

The nucleotide sequence of Mycoplasma mycoides sp. capri PG3 formylmethionine tRNA has been determined, using in vitro labeling techniques, to be pC-G-C-G-G-G-G-s4U-A-G-A-G-C-A-G-U-D (U)-G-G-D-A-G-C-U-C-G-C-C-G-G-G-C-U-C-A-U-A-A-C-C-C-G-G-A-G-G-C-C-G-C-A-G-G-U-psi- C-G-A-G-U-C-C-U-G-C-C-C-C-C-G-C-A-A-C-C-AOH. This tRNA contains only three modified nucleosides s4U, D and psi, all of which are derived from uridine. Both in the structural features which distinguish eukaryotic from prokaryotic initiator RNAs and in the overall sequence, this tRNA resembles a typical prokaryotic initiator tRNA. A comparison of the sequence of this tRNA with those of other prokaryotic initiator tRNAs suggests that taxonomically the Mycoplasma may be less related to the Cyanophyta (Anacystis nidulans) than to the bacteria and less related to the Enterobacteriaceae (Escherichia coli) than to the Bacillaceae (Bacillus subtilis).
