What is the minimum number NTPs requred for formation of one peptide bond during protein synthesis?
Two NTPs are required for the formation of one peptide bond during protein synthesis. Specifically, one NTP is needed for charging the tRNA with the corresponding amino acid, and a second NTP is required for the actual bond formation in the ribosome.
Is a peptide bond a covalent bond?
Yes, a peptide bond is a type of covalent bond that forms between the carboxyl group of one amino acid and the amino group of another amino acid during protein synthesis.
What is the name of the enzyme that causes the formation of the peptide bonds between amino acids during translation of protein synthesis?
The enzyme responsible for forming peptide bonds between amino acids during protein synthesis is called peptidyl transferase. It is a ribozyme found in the ribosome.
What chemical reaction makes a peptide bond?
A peptide bond is formed through a condensation reaction between the carboxyl group (-COOH) of one amino acid and the amino group (-NH2) of another amino acid. This reaction results in the release of a water molecule.
What type of bond is unique to proteins?
Peptide bonds are the type of bond that is unique to proteins. Peptide bonds form between the carboxyl group of one amino acid and the amino group of another amino acid during protein synthesis.
What does protein synthesis consist of?
peptide
What are some identifiers for the c peptide?
The connecting peptide, or C-peptide, is a short 31-amino-acid protein that connects insulin's A-chain to its B-chain in the proinsulin molecule. In the insulin synthesis pathway, first preproinsulin is secreted from the beta cells of the pancreas with an A-chain, a C-peptide, a B-chain, and a signal sequence. The signal sequence is cleaved from the N-terminus of the peptide by a signal peptidase, leaving proinsulin. Then the C-peptide is removed, leaving the A-chain and B-chain that constitute the insulin molecule.
Peptide hormones that are synthesized as a large precursor homone is called?
prohormones. These prohormones are inactive and need to be cleaved or modified to become biologically active peptide hormones.
In protein synthesis a nucleus forms peptide bonds?
In protein synthesis, peptide bonds are formed in the ribosome, not in the nucleus. The nucleus is responsible for housing the DNA and transcribing it into messenger RNA (mRNA) for protein synthesis to occur in the ribosome.
What is the minimum number NTPs requred for formation of one peptide bond during protein synthesis?
Two NTPs are required for the formation of one peptide bond during protein synthesis. Specifically, one NTP is needed for charging the tRNA with the corresponding amino acid, and a second NTP is required for the actual bond formation in the ribosome.
What type of bonds join phosphate groups to the sugers?
Peptide bonds
How is ADP made from ATP?
ADP is made by ATP when one of three peptide bonds of ATP are broken down.
What is peptide transferase?
Peptidyl transferase is the enzyme that catalyzes the formation of peptide bonds between amino acids during translation of protein synthesis.
What kind of a reaction forms a peptide bond?
dehydration synthesis
What process produces peptide bonds?
A dehydration synthesis reaction forms peptide bonds between amino acids by removing a water molecule. In this process, the carboxyl group of one amino acid reacts with the amine group of another amino acid, resulting in the formation of a peptide bond and a dipeptide molecule.
What is the mature form of insulin?
Insulin like many other peptide hormones is synthesized in the body as a pro-hormone that is then cleaved to become the more active hormone. Therefore the mature form could be said to the cleaved active horomone and not the 'juvenile' pro-hormone (actually used clinically as pro-insulin). However, in humans, the insulin of adults is the same as that of children.
Which type of reaction are essentially opposites of one another?
Decomposition and synthesis, peptide bonding and hydrolysis, etc.
