AMINOACIL ARNT SINTETASA PDF

It does so by catalyzing the esterification of a specific cognate amino acid or its precursor to one of all its compatible cognate tRNAs to form an aminoacyl-tRNA. In humans, the 20 different types of aa-tRNA are made by the 20 different aminoacyl-tRNA synthetases, one for each amino acid of the genetic code. This is sometimes called "charging" or "loading" the tRNA with the amino acid. Once the tRNA is charged, a ribosome can transfer the amino acid from the tRNA onto a growing peptide , according to the genetic code.

Growth and protein synthesis rates of P. AARS activity is valid as index of somatic growth for P. However, the relationship between protein-specific AARS activity and nauplii growth varied according to food availability levels. The results presented here add to previous studies showing that the AARS activity is a useful tool for estimating somatic growth of this and other key copepod species.

Nevertheless, further research is required to elucidate the validity of AARS activity as a universal proxy for growth. Page view s 8. Download s Google Scholar TM Check. Effect of temperature and food concentration on the relationship between growth and AARS activity in Paracartia grani nauplii.

Herrera, I. The in situ activity of the enzymes aminoacyl-tRNA synthetases AARS and the growth rates of naupliar stages of the planktonic marine copepod Paracartia grani were measured in the laboratory under different temperature and food concentrations.
