Every item is shipped based on the best shipping method assessed for the temperature requirements of that specific item. Items are grouped and shipped together whenever
possible, and a separate shipping charge will be included for each shipping method required. Shipping charges listed below are from our US warehouses to the Contiguous US,
Alaska, Hawaii, Canada and Puerto Rico. Shipping charges for countries outside the US and Canada will be determined once order has been received
Please note: We can not ship to PO boxes

Aminoacyl-tRNA synthetases function to catalyze the aminoacylation of tRNAs by their corresponding amino acids, thus linking amino acids with tRNA-contained nucleotide triplets. GlnRS (Glutaminyl-tRNA synthetase), also known as QARS, is a 775 amino acid member of the class-I aminoacyl-tRNA synthetase family. Localized to the cytoplasm, GlnRS is part of a multi-protein complex composed of nine aminoacyl-tRNA synthetases that are specific for nine amino acids, namely Arg, Asp, Glu, Gln, Ile, Leu, Lys, Met and Pro. In this complex, GlnRS functions to catalyze the ATP-dependent conversion of L-glutamine (Gln) and tRNA(Gln) to Gln-tRNA(Gln). While GlnRS is used to synthesize Gln-tRNA(Gln) in many eukaryotic cells, prokaryotes and organelles, such as mitochondria and chloroplasts, can synthesize Gln-tRNA(Gln) in a two step process involving misacylation and amidation reactions.
