Crystal structure of tryptophanyl tRNA synthetase II from Deinococcus radiodurans in complex with 5-Hydroxy tryptophan.
Overview
The most divergent of two tryptophanyl tRNA synthetases (TrpRS II) found in Deinococcus radiodurans interacts with a nitric oxide synthase protein that produces 4-nitro-tryptophan (4-NRP). TrpRS II efficiently charges transfer RNA(Trp) with 4-NRP and 5-hydroxy-tryptophan (5-HRP). The crystal structures of TrpRS II bound to tryptophan and 5-HRP reveal residue substitutions that accommodate modified indoles. A class of auxiliary bacterial TrpRSs conserve this capacity to charge tRNA with nonstandard amino acids.
About this Structure
1YIA is a Single protein structure of sequence from Deinococcus radiodurans r1 with as ligand. Active as Tryptophan--tRNA ligase, with EC number 6.1.1.2 Full crystallographic information is available from OCA.
