Enzymsystem med en enda underenhet och som endast kräver magnesium för endonukleolytisk verkan. Motsvarande modifieringsmetylaser är separate enzymer. Systemen känner igen specifika, korta DNA-sekvenser och klyver inom, eller på ett kort, specifikt avstånd från, den igenkända sekvensen, vilket ger specifika, dubbelsträngade fragment med 5'-fosfatändar. Enzymer från olika mikroorganismer med samma specificitet kallas isoschizomerer. EC 3.1.21.4.
Enzyme systems containing a single subunit and requiring only magnesium for endonucleolytic activity. The corresponding modification methylases are separate enzymes. The systems recognize specific short DNA sequences and cleave either within, or at a short specific distance from, the recognition sequence to give specific double-stranded fragments with terminal 5'-phosphates. Enzymes from different microorganisms with the same specificity are called isoschizomers. EC 3.1.21.4.
