Thousands of APS thus remain to be defined molecularly. Selected recent examples highlighting an astonishing molecular diversity of these defence systems are described in this editorial. The mechanisms include allosterically regulated dGTPase responding to competing nucleotide signals (Clover); bacterial defence systems activated by phage anti\u2010defence manoeuvres (Panoptes); a prophage encoded tRNA nuclease activated by a phage tail tip protein (HepS); a helicase\u2010nuclease complex that scans for ssDNA 3\u2032 overhangs created by phage DNA transaction (Hachiman); and systems that cleave free ends of linear DNA (Shedu). Systems were described that synthesize template\u2010free poly\u2010dA chains which are degraded by a phage exonuclease thereby activating an ion channel (Hailong). Several systems interfere with phage DNA injection into the cell, for example, a cell membrane associated protein complex inhibiting injection (KIWA); or destroying phage DNA at injection (SNIPE); or a complex membrane motor system that senses phage DNA injection and activates nuclease effectors (Zorya). Other systems consist of a single pore building protein that combines sensor and effector functions (Rip1) or degrade NAD\n                    <jats:sup>+<\/jats:sup>\n                    (Cat1). Defence\u2010associated reverse transcriptase (DRT) preceded by non\u2010coding RNA (ncRNA) come in different forms: in DRT2 a rolling circle reverse transcription leads to an endless protein inducing cell dormancy; in DRT3 a mixed templated and untemplated repeat DNA synthesis becomes cytotoxic in presence of a phage protein; DRT9 synthesizes a polyA strand that might sequester a phage protein needed for DNA replication. Striking are bacterial APS that resemble innate immune reaction directed against viruses in animals (gasdermin, Argonaute, RAZR, Schlafen, Thoeris 2, ubiquitin\u2010like proteins) pointing to an ancient origin.\n
