Life Cycle of the Phage

M13 phage proteins

NCBI link to seq: [[1]]
Source: Phage Display of Peptides and Proteins: a laboratory manual. Kay, Winter, McCafferty. Ch 1. [[2]]

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
