different kinds of enzyms / nomenclature of enzyms:

Normally the name of an enzyme start with the substrate name + immediately thereafter the activity of that enzyme + suffix -ase.

Oxyreductases catalyse redox reactions (for example: glucose-oxidase)
Transferases transport functional groups of a donator to a receiver
Hydrolases split molecules (for example: peptidases, proteases)
Liases distract or add: certain functional groups (for example: decarboxylase)
Isomerases change isomeres (mutase)
Ligases connect different molecules with each other (piruvaate carboxylase)
