The differences between kinases, ligases and synthases


Firstly , all these are kinds of enzymes that do particular kinds of things in living systems.

A kinase is an enzyme associated with energy production. It is involved in transfering phosphate groups from one molecule to another. Effectively it energises a molecule so it can go onto a new reaction.

kinase

Involved in energy and metabolism. Kin- kinetic, or to move energy


A ligase is a kind of enzyme that helps to join molecules togther. For example DNA is a string of nucleic acids. These need to be joined and a DNA ligase is used. The enzyme needs to be shaped to fit part of the DNA or RNA molecule.

ligase

A DNA ligase. involved in joining molecules together ; lig- ligate or join


Synthases are enzymes usually involved in the production of a particular kind of biochemical. For example Tryptophan synthase, helps in the the last step for creating Tryptophan. Or ATP-synthase produces a final ATP molecule.

synthase

ATP-synthase. produce a particular kind of biochemical molecule; synth- to create or make



How they all work together

note: DNA ligase can just use ATP with no kinases
