 1-71 1.01e-31

holin, SPP1 family; This model represents one of more than 30 families of phage proteins, all lacking detectable homology with each other, known or believed to act as holins. Holins act in cell lysis by bacteriophage. Members of this family are found in phage PBSX and phage SPP1, among others. [Mobile and extrachromosomal element functions, Prophage functions]

 1-64 2.41e-18

SPP1 phage holin; This family constitutes holin proteins from the dsDNA Siphidoviridae group bacteriophages with two transmembrane segments. Most bacteriophages require an endolysin and a holin for host lysis. During late gene expression, holins accumulate and oligomerise in the host cell membrane. They then suddenly trigger to permeablise the membrane, which causes lysis by allowing endolysin to attach the peptidoglycan. There are thought to be at least 35 different families of holin genes.
