Phosphorylation of elongation factor-1 (EF-1) by cdc2 kinase.
Paris, France. In Prog Cell Cycle Res, 1994
The guanine-nucleotide exchange factor EF-1 beta gamma delta, appears to have a highly complex macromolecular structure containing several GTP/GDP exchange proteins, valyl-tRNA synthetase, and a putative anchoring protein EF-1 gamma.
Partition of tRNA synthetases into two classes based on mutually exclusive sets of sequence motifs.
Strasbourg, France. In Nature, 1990
Out of the 18 known aaRS, only 9 referred to as class I synthetases (GlnRS, TyrRS, MetRS, GluRS, ArgRS, ValRS, IleRS, LeuRS, TrpRS), display two short common consensus sequences ('HIGH' and 'KMSKS') which indicate, as observed in three crystal structures, the presence of a structural domain (the Rossman fold) that binds ATP.
