what is difference between kinases,ligases,synthase,synthatase?

Answer 1

First and foremost is the fact that any molecule that has a name ending in "ase" is an enzyme, therefore it acts to speed up a reaction in the presence of the appropriate reactants and co-factors.

Kinases are enzymes that act on specific substrate molecules, whether they be protein, lipid, carbohydrate, etc and phosphorylate them.

Ligases act to join to different molecules together such as DNA ligases, ubiquitin ligases, etc.

Synthases act, often as a large multicomponent complex to generate specific complex macromolecules, such as was mentioned for ATP synthases.

Transferases take specific sub-groups and "transfer" them from one molecule to another or even within the same molecule.

Acetylases modify substrates by the addition of acetyl groups.

The list goes on, but the names give you a pretty good hint as to what the enzyme does.

Answer 2

kinases are involved in 'energizing' molecules that go onto further reactions.

Ligases are involved in joining molecules togther, most typically DNA ligases join DNA strands.

Synthases are usually involved in the final steps of the production of an important biochemical. eg ATP-synthase produces a final ATP molecule that gets almost immediatly used by a kinase.

Answer 3

kinase is an enz which helps in phosphorylating the substrate to give a product .eg:in glycolysis glucose is phosphorylated to form Glucose-6-phosphate in the presence of hexokinase.Ligase is an enz which is involved in ligating ie joining.these enzs are mostly used in rDNA tech.Synthase is an enz which helps in synthesis of product( i m not sure abt this)
