 A2 holin family

The Putative Archaeal 2 TMS Holin (A2-Hol) Family (TC# 9.B.109) consists of a few putative holins from "Thaumarchaeota" ranging in size from about 130 to 165 amino acyl residues (aas) and exhibiting 2 transmembrane segments (TMSs).A representative list of proteins belonging to the A2-Hol family can be found in the Transporter Classification Database.
