crystal structure of tRNAVal in complex with archaeosine tRNA-guanine transglycosylase at 3.3 A resolution. The enzyme binds a different tRNA conformation (lambda form), in which the canonical core is completely disrupted and the melted D arm is protruded. The PUA domain is found to be crucial for the precise location of the tRNA molecule on the enzyme
