Questions and Answers

What is the role of the amino acyl tRNA synthetase in the process of protein synthesis?

The amino acyl tRNA synthetase catalyzes the formation of a covalent bond between a specific amino acid and a charged transfer RNA (tRNA) molecule, which is necessary for the process of translation.

What is the role of ATP in the process of aminoacyl tRNA synthesis?

ATP is required to activate the amino acid and allow it to bind to the specific aminoacyl tRNA synthetase enzyme.

What is the role of ATP in the process of aminoacyl tRNA synthesis?

ATP provides energy for the formation of a covalent bond between the amino acid and the tRNA molecule.

Describe the process of aminoacyl tRNA synthetases catalyzing the deformation of tRNA and amino acid binding.

<p>A specific amino acyl tRNA synthetase binds a particular amino acid and ATP in its active site, forming a covalent bond between the amino acid and the carboxyl group of the tRNA. A pyrophosphate is released from the enzyme, and a specific tRNA with an anticodon complementary to the amino acid binds to the entities. The bond between the amino acid and ATP is broken, and a covalent bond is formed between the amino acid and the tRNA's 3' end, which is now a charged tRNA molecule.</p> Signup and view all the answers
