pPVC promoter->pvc1-pvc12->pvc13_NTD-2*Bsal-pVc13_CTD->pvc14-pvc16

Structural and accessory genes

Profile

Name:pvc1-pvc12,pvc13_NTD-2*Bsal-pVc13_CTD,pvc14-pvc16
Base Pairs: 19360bp
Origin: Photorhabdus
Properties: Structural and accessory genes

Usage and Biology

This part is necessary for the assembly of a functional injection system. PVCs probably recognize target cells via tail fibres (Pvc13), leading to a contraction of the sheath mechanism that drives a spike through the cellular membrane.[1]
Pvc2, Pvc3 and Pvc4 compose the sheath of PVC. Pvc16 is sheath terminator of PVC. Pvc13 is tail fibres of PVC. Pvc9, Pvc11 and Pvc12 compose the baseplate of PVC. Pvc8 and Pvc10 compose the spike of PVC. Pvc1, Pvc5 and Pvc7 compose the tube of PVC.[2]（Fig.1)
This part has a Bsal enzyme recognizing sequence, which can allow to use the way Golden Gate Assembly to construct a plasmid.(Fig.2(a),Fig2(b))
