1.E.69. The Caudoviricetes Holin (CVH) Family This family includes several homologs of small proteins with two C-terminal TMSs. They seem to be of various lengths. Their function as a holin seems not to be well established.
Examples:
TC#	Name	Organismal Type	Example
1.E.69.1.1	Holin of 131 aas with two C-terminal TMSs.		Holin of Caudoviricetes sp. (hot spring metagenome)

1.E.69.1.2	Putative holin of 75 aas with 2 C-terminal TMSs.		Putative holin of Nitrososphaerales archaeon
