Crystal structure of tryptophanyl trRNA synthetase II from Deinococcus radiodurans in complex with L-Trp
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
1YI8 is a Single protein structure of sequence from Deinococcus radiodurans r1 with TRP as ligand. Full crystallographic information is available from OCA.
