1.E.37 The Phage T1 Holin (T1 Holin) Family
This family is represented in enterobacterial phages T1, RTP and F20 as well as Klebsiella phage KP36 and Escherichia phage ADB-2. All of these possess a putative holin that share a high level of identity. Additionally, Gp9 of E. coli phage phiE49 is similar in sequence. These proteins are short (55-71 aas) and have a single TMS (Catalão et al. 2012).
