Abstract excerpt
A randomly generated mutation in Escherichia coli alanine tRNA synthetase compensates for a mutation in its cognate tRNA. The enzyme's mutation occurs next to a Cys-X2-Cys-X6-His-X2-His metal-binding motif that is distinct from the zinc finger motif found in some DNA-binding proteins. Instead, the synthetase's metal binding domain resembles the Cys-X2-Cys-X4-His-X4-Cys metal-binding domain of the gag gene product...
