rhTyrRS is a functional aminoacyl-tRNA synthetase. A: The ability of rhTyrRS to charge tRNA with ³H-labeled tyrosine was tested in vitro as a function of rhTyrRS concentration and time. The following concentrations of rhTyrRS were tested: 320 nM, 160 nM, 80 nM, 40 nM, 20 nM, and 10 nM. B: The ability of rhTyrRS to charge tRNA after 4 and 6 min.
