Does carboxypeptidase digest proteins?
Yes.
What is the substrate of carboxypeptidase?
The substrate of carboxypeptidase is a peptide or protein molecule with a terminal amino acid that contains a free carboxyl group. Carboxypeptidase cleaves this terminal amino acid from the substrate by hydrolyzing the peptide bond.
What enzyme works in the opposite direction of carboxypeptidase?
Aminopeptidase
What organ secretes carboxypeptidase?
Carboxypeptidase is secreted by Pancreas in inactive form (procarboxypeptidase) and is activated by trypsin. Carboxypeptidase is also secreted by small intestine as brush border enzyme. Reference: Human Anatomy and Physiology by Elaine N. Marieb
What enzyme does carboxypeptidase break down?
Carboxypeptidase breaks down peptides by cleaving off individual amino acids from the C-terminal end of the peptide chain.
What converts polypeptides into smaller polypeptides during digestion?
Aminopeptidase & carboxypeptidase
How does amino peptidase differ from carboxypeptidase in terms of protein digestion?
The two enzymes differ based on where they cleave the protein being digested. The amino peptidase cleaves the protein from the amino terminus while the carboxypeptidase cleaves the protein from the carboxy terminus.
What enzymes will hydrolyze proteins by removing amino acids from the end of the molecules and not by hydrolyzing bonds within the molecules?
carboxypeptidase
Zinc an essential trace element for most organisms is present in the active site of the enzyme carboxypeptidase The zinc most likely functions as a?
Zinc in the enzyme carboxypeptidase likely functions as a cofactor, helping to stabilize the enzyme's structure and assist in catalyzing the reaction by participating in binding and activation of the substrate.
What has the author Eric Portelance written?
Eric Portelance has written: 'The effect of carboxypeptidase N on small cell lung carcinoma cells'
What has the author Susan Maria Certossi written?
Susan Maria Certossi has written: 'Identification of creative kinase conversion factor as carboxypeptidase N'
What is the function of zinc in the active site of the enzyme carboxypeptidase?
Zinc serves as a cofactor in the active site of carboxypeptidase by stabilizing the reaction intermediate during peptide cleavage. It acts as a Lewis acid, facilitating the nucleophilic attack on the peptide bond. Zinc also helps orient the substrate in the active site for optimal binding and catalysis.
