Research Our recent work has concentrated on the diverse roles of transfer RNA in various biological systems. We have focused on the evolutionary role of non-canonical components of the translational machinery. In particular, we are investigating the extensive use of transfer RNA-dependent amino acid transformations as the essential route to the synthesis of Asn-tRNA and Gln-tRNA in a vast variety of organisms. In addition, we are characterizing the mode of action of a novel bi-functional prolyl-tRNA synthetase which also forms Cys-tRNA, an enzyme present in archaea and lower eukaryotes. These findings redefine our understanding of aminoacyl-tRNA synthesis and provide novel insight into the possible origins of protein biosynthesis.
