1QQT - PubMed Abstract: 
The 3D structure of monomeric C-truncated Escherichia coli methionyl-tRNA synthetase, a class 1 aminoacyl-tRNA synthetase, has been solved at 2.0 A resolution. Remarkably, the polypeptide connecting the two halves of the Rossmann fold exposes two identical knuckles related by a 2-fold axis but with zinc in the distal knuckle only ...
