What are the different types of DNA Isomerases?

Isomerases are further classified into six subclasses:

• Racemases, epimerases.
• Cis-trans isomerases.
• Intramolecular oxidoreductases.
• Intramolecular transferases.
• Intramolecular lyases.
• Ring expansion and contraction via tautomers.
• Epimerization.
• Intramolecular transfer.

What is isomerase and examples?

Isomerases are enzymes that catalyze the formation of a substrate’s isomer. Some examples of isomerases include triose phosphate isomerase, bisphosphoglycerate mutase, and photoisomerase. Isomerases can help prepare a molecule for subsequent reactions such as oxidation-reduction reactions.

Where are Isomerases found?

Isomerases are present in the metabolism and genome of most living organisms, catalysing up to 4\% of the biochemical reactions present in central metabolism, in particular, carbohydrate metabolism.

What is the function of the Isomerases?

Thus, a ketose is formed and then the ring is closed again. Isomerase has a broad array of functions in everything from medicine to food manufacture. Deficiencies in isomerases have been known to lead to diseases in humans such as Phosphohexose isomerase deficiency and Triosephosphate isomerase deficiency.

What do oxidoreductases do?

oxidoreductase, any member of a class of enzymes, commonly known as dehydrogenases or oxidases, that catalyze the removal of hydrogen atoms and electrons from the compounds on which they act.

What are examples of oxidoreductases?

Articles in Proteopedia concerning Oxidoreductases include:

• Alcohol Dehydrogenase or Tetrameric alcohol dehydrogenases.
• Aromatase.
• Catalase (Hebrew)
• Choline Oxidase.
• CotA laccase.
• Ceruloplasmin.
• Dihydrofolate reductase.
• Dihydrolipoamide dehydrogenase.

What types of reactions do Isomerases catalyze?

isomerase, any one of a class of enzymes that catalyze reactions involving a structural rearrangement of a molecule. Alanine racemase, for example, catalyzes the conversion of L-alanine into its isomeric (mirror-image) form, D-alanine.

What type of reactions do Isomerases catalyze?

What are ligases what is their importance?

In biochemistry, a ligase is an enzyme that can catalyze the joining (ligation) of two large molecules by forming a new chemical bond. Ligase can join two complementary fragments of nucleic acid and repair single stranded breaks that arise in double stranded DNA during replication.

What are oxidoreductases give example?

Oxidoreductases, or EC 1, catalyze oxidation/reduction reactions. They speed up the transfer of electrons from an electron donor to an electron acceptor. Examples are alcohol oxidoreductases and aldo-keto reductases.
