Ligand gated
Ligand gated ion channels/receptors are large multisubunit complexes which are usually pentamers (5 subunits) that form an ion channel in the membrane. The complex may be heteromeric in that it is composed…
Types of hormones

Topoisomerases
DNA topoisomerases are able to modify the termtiary structure of circular DNA. Prokaryotic enzymes do not require ATP, as do eukaryotic topoisomerases. DNA topoisomerases have been classified into two types:…
Polymerases
Polymerases are enzymes which polymerize new DNA or RNA using an existing DNA or RNA template. Polymerases are essential in DNA replication and transcription. PARPS See outline Tankyrasses (TANKs) TANKs…
Oxidoreductases
An oxidoreductase is an enzyme that catalyzes the transfer of electrons from one molecule called "the reductant" or "electron donor" to another molecule called "the oxidant" or the "electron acceptor". This group…
Neuraminidases
Neuraminidases (also known as sialidases): are enzymes that have been identified in many viruses, bacteria and eukaryotes that cleave sialic acid moieties and can be involved in many functions in vivo. It has…
