Serine betalactamases are a subgroup of the betalactamases.
Among the betalactamases there is a variety of different classes and variants (>340). They are either chromosomally or plasmid-coded. Their chemical structure is different. Most betalactamases are serine betalactamases. They have a serine molecule in their active centre. Other rare betalactamases have a central zinc ion(metallobetalactamases).
