γ-Glutamyl kinase is involved in selective autophagy of ribosomes in Saccharomyces cerevisiae.

abstract：:The kinetics of the tRNA cycle is in itself capable of keeping the translational error level almost unaffected by amino acid starvation. There is no need to assume any yet unknown mechanism or property. Kinetic analysis shows that the concentration of aminoacyl-tRNA can stay high even for large reductions in aminoacyl...
