tRNA-m1G methyltransferase interactions: touching bases with structure.
m1G methyltransferase of Escherichia coli is being examined with regard to how specific tRNA substrates are recognized. This enzyme appears to require the entire tRNA structure of optimal activity. Recognition may require specific base contacts as well as phosphate backbone structures embodied in the tRNA structure.
