The Enterobacterial Holin (EBHol) Family (
TC# 1.E.48) consists of many closely related proteins of 100 to 120 amino acyl residues (aas) in length with a single C-terminal transmembrane segment (TMS). They derive from
γ-proteobacteria of many
genera: Salmonella,
Escherichia,
Klebsiella and
Photorhabdus, and their
phage. As of March 2016, these proteins have not been functionally characterized. A representative list of proteins belonging to the EBHol family can be found in the
Transporter Classififcation Database.[1]
