[Primary structure of yeast mitochondrial tryptophan-tRNA capable of translating the termination U-G-A codon].
The primary structure of Yeast Saccharomyces cerevisiae mitochondrial tryptophane-tRNA, isolated by reversed phase chromatography and two-dimensional gel electrophoresis has been determined. It is as follows: pA-A-G-G-A-U-A-U-A-G-U-U-U-A-A-D-G-G-D-A-A-A-A-C-A-G-U-U-G-A-psi-U-U-C-A-i6 A (ms2i6 A)-A-psi-C-A-A-U-C-A-U-U-A-G-G-A-G-T-psi-C-G-A-A-U-C-U-C-U-U-U-A-U-C-C-U-U-G-C-C-A. Owing to its anticodon U-C-A-, where U represents a modified uridine, this tRNA can translate the opal codon U-G-A, which is usually a protein synthesis termination codon in cytoplasmic systems.
