holins

Holins are a class of proteins that play a crucial role in the regulation of bacterial cell division. They are named for their ability to "hold" the cell together, preventing premature separation of the daughter cells. Holins are typically found in Gram-negative bacteria and are essential for the proper functioning of the cell division machinery.

The holin protein is usually encoded by a gene located downstream of the cell division gene, FtsZ,

The formation of holin pores is a critical step in the cell division process. It allows the

In some bacteria, holins are also involved in the regulation of antibiotic resistance. For example, in Escherichia
