| protein | aa (mature) | function | notes |
|---|---|---|---|
| I | 348 | assembly | includes gXI within, the two form structure in cytoplasmic membrane for phage maturation |
| II | 410 | replication of DNA + strand | includes gX within |
| III | 406 | phage tail protein (5 copies) | tag at N-term |
| IV | 405 | assembly | organizes to pore in OM |
| V | 87 | binds ssDNA | recognizes DNA PS |
| VI | 112 | phage tail protein (5 copies) | packages with pIII |
| VII | 33 | phage head protein (5 copies) | packages with p9 |
| VIII | 50 | phage coat protein (2700 copies) | seg seq cleaved, matured form at aa 23 = clones to N-term, "Petrenko" site [[3]] |
| IX | 32 | phage head protein (5 copies) | stop codon overlaps start of gVIII |
| X | 111 | DNA replication | internal reinitiation inside gII |
| XI | 108 | assembly | translation reinitiation inside gI |
