WebApr 1, 2024 · The specific activity (0.023 nmol product formed min −1 per nmol of enzyme) is in the same range as that calculated for other [4Fe-4S]-dependent tRNA thiolation enzymes tested in similar conditions (for example 0.035 nmol min −1 nmol −1 for E. coli TtcA 38, using E. coli ΔttcA bulk tRNA as a substrate). The rather low catalytic activity ... WebJan 3, 2024 · 1. Making Aminoacyl-tRNAs. Translation is perhaps the most energy-intensive job a cell must do, beginning with the attachment of amino acids to their tRNAs. The basic amino-acylation reaction is the same for all amino acids. A specific aminoacyl-tRNA synthase attaches each tRNA to ( charges) an appropriate amino acid.
