C-terminal (CT) domain of the contact-dependent growth inhibition (CDI) system (CdiA-CT) of Burkholderia pseudomallei, and similar proteins
CDI toxins are expressed by gram-negative bacteria as part of a mechanism to inhibit the growth of neighboring cells. This model represents the C-terminal (CT) toxin domain of CdiA effector proteins. CdiA secretion is dependent on the outer membrane protein CdiB. Upon binding to a receptor on the surface of target bacteria, the CDI toxin is delivered via the C-terminal domain. A wide variety of C-terminal toxin domains appear to exist; this particular model includes the C-terminal (CT) toxin domains of Burkholderia pseudomallei E479 and 1026b, both appearing to be RNAses acting on tRNA.

Evidence:
  • Comment:CdiA protein binds neighboring bacteria and delivers C-terminal toxin domain (CdiA-CT) to inhibit target-cell growth; CdiI immunity protein specifically neutralizes cognate CdiA-CT toxin to prevent self-inhibition
