What are examples of oligomeric enzymes?

Lactate dehydrogenase: Vertebrate lactate dehydrogenase (LDH) is an example of an oligomeric enzyme where each sub-unit has the same function,to catalyse the conversion of lactate to pyruvate.

What is a monomeric enzyme?

Monomeric enzymes are enzymes consisting of a single polypeptide chain or subunit.

What is monomeric and oligomeric enzymes?

(a) Monomeric enzymes: Consist of one polypeptide chain (subunit), e.g., ribonuclease, lysozyme, hexokinase etc. (b) Oligomeric enzymes: Consist of more than one oolypeptide chain. They are functional in their quaternary structure.

What is allosteric enzyme quizlet?

what is an Allosteric Enzyme? An enzyme with multiple binding sites, an Active site and an Allosteric Site. Allosteric enzymes can alternate between active & inactive forms.

Is hemoglobin an oligomeric?

Oligomeric proteins include the hemoglobins, allosteric enzymes responsible for the regulation of metabolism, contractile proteins such as actin and tubulin, and cell membrane proteins.

What are oligomers called?

An oligomer of amino acids is called an oligopeptide or just a peptide. An oligonucleotide is a short single-stranded fragment of nucleic acid such as DNA or RNA, or similar fragments of analogs of nucleic acids such as peptide nucleic acid or Morpholinos.

What is monomeric unit?

A group of atoms, derived from a molecule of a given monomer (def. 1), that comprises any one species of constitutional unit of a polymer. From: monomeric unit in Oxford Dictionary of Biochemistry and Molecular Biology »

What is a dimeric enzyme?

dimer A protein that is made up of two polypeptide chains or subunits paired together. An example of a dimeric enzyme is glucose–phosphate isomerase. Some enzymes are trimeric (comprising three components) or tetrameric (with four components).

What kind of enzyme is pepsin?

Pepsin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pepsin as an inactive zymogen called pepsinogen. Parietal cells within the stomach lining secrete hydrochloric acid that lowers the pH of the stomach.

What is Homotropic?

Medical Definition of homotropic : characterized by enzyme activity in which the substrate binds to the enzyme at two different sites of which one is the normal reactive site and the other is an allosteric site homotropic enzymes homotropic interaction — compare heterotropic.
