Functional Families

Overview of the Structural Clusters (SC) and Functional Families within this CATH Superfamily. Clusters with a representative structure are represented by a filled circle.

Superfamily: CRISPR-associated endonuclease Cas1, N-terminal domain

Clustered regularly interspaced short palindromic repeats (CRISPRs) are a family of DNA direct repeats found in many prokaryotic genomes. This family of proteins corresponds to Cas1, a CRISPR-associated protein. Cas1 may be involved in linking DNA segments to CRISPR.

This superfamily entry represents the CRISPR-associated endonuclease Cas1, N-terminal beta-sandwich-like domain. Cas1 may play a role in the recognition, cleavage, and/or integration of foreign nucleic acids into CRISPRs.
