RNA-guided endonuclease TnpB family protein, partial [Escherichia coli]

Protein Classification

RNA-guided endonuclease InsQ/TnpB family protein( domain architecture ID 11430747)

RNA-guided endonuclease InsQ/TnpB family protein such as the RNA-guided endonuclease TnpB from IS200/IS605 family elements and IS607 family elements; this protein is homologous to some CRISPR-associated (Cas) proteins such as the type V CRISPR-associated protein C2c8; TnpB proteins were described as accessory proteins in IS (insertion sequence) elements, present as one of just one or two proteins encoded in the element but not necessary for transposition. The programmable RNA-guided endonuclease TnpB proteins may provide a CRISPR-like, widespread form of phage defense by RNA-guided DNA degradation.

Putative transposase DNA-binding domain; This putative domain is found at the C-terminus of a large number of transposase proteins. This domain contains four conserved cysteines suggestive of a zinc binding domain. Given the need for transposases to bind DNA as well as the large number of DNA-binding zinc fingers we hypothesize this domain is DNA-binding.
