This image depicts the binding of tRNA synthetase to transfer RNA. The
synthetase protein is depicted as a Richardson (MolScript) style cartoon
depicting beta-strands with arrows and helices as ribbons. The protein
alpha helices are shown in magenta, beta sheets are shown in yellow and
random coil as a white alpha carbon trace. The TRNA backbone is shown
as parallel red strands, with the outermost strand coloured white. The
bound ATP cofactor is shown as spacefilling CPK spheres and the locations
of crystallographic waters depicted as black "dot" spheres.
