Type I restriction enzymes are a group of endonucleases that recognize a bipartite sequence, but do not produce a predictable cleavage pattern.

Type I restriction enzymes (REases) are large pentameric proteins with separate restriction (R), methylation (M) and DNA sequence-recognition (S) subunits.

In molecular biology, endonucleases are enzymes that cleave the phosphodiester bond within a polynucleotide chain (namely DNA or RNA).

They recognise asymmetric DNA sequences split into two domains of specific sequence, one 3-4 bp long and another 4-5 bp long, separated by a nonspecific spacer ...

Type I restriction endonuclease holoenzymes contain methylase (M), restriction (R) and specificity (S) subunits, present in an M2:R2:S1 stoichiometry.

The Type I and III restriction endonucleases are large, multimeric protein complexes with four enzyme activities; DNA methyltransferase, DNA endonuclease, ...

Restriction enzymes are also called molecular scissors as they cleave DNA at or near specific recognition sequences known as restriction sites.
