Short name: i-spanin_T7likevirus

Description

The lysis of Gram-negative hosts by double-strand DNA bacteriophages requires, in addition to the actions of a holin and endolysin, a third step involving the spanin complex. This complex consists of a small outer membrane lipoprotein and an integral cytoplasmic membrane protein, designated as o-spanins and i-spanins, respectively. The spanin complex is involved in the disruption of the outer membrane. Without spanin function, lysis is blocked and progeny virions are trapped in dead spherical cells [PMID: 24585055].

This entry represents the i-spanin subunit, mainly from T7-like viruses.
