symbiont genome ejection through host cell envelope symbiont genome ejection through host cell envelope, long flexible tail mechanism https://github.com/geneontology/go-ontology/issues/26670 Entry of a symbiont's genome into the host cell through the host cell envelope via a long, flexible tail ejection system consisting a baseplate, a central tube and a terminator complex which attaches the tail to the phage capsid. Upon binding to the host cell surface, the baseplate changes its conformation and triggers genome ejection into the host cell cytoplasm. Occurs in non-enveloped prokaryotic viruses. biological_process viral genome ejection through host cell envelope, long flexible tail mechanism VZ:3952 GO:0099001 viral long flexible tail ejection system
