Structural and accessory genes
Profile
Name:pvc1-pvc12,pvc13_ NTD-CKGGRAKDC-pVc13_CTD,pvc14-pvc16
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]
This part also has a special sequence CKGGRAKDC(Fig.1), which can recognize our target cells, making PVC tropism toward specific cells.
Special Design
This part has a special sequence CKGGRAKDC, which can recognize our target cells.
