• Naturally present in Lactococcus lactis subsp. cremoris DCH-4 (Moineau et al., 1995)
  
• Size: 7.8 kb (Moineau et al., 1995)
  
• Encodes a restriction/modification system named LlaDCHI (Moineau et al., 1995)
  
• Confers strong phage resistance to phage-sensitive L. lactis strain against lactococcal phage species 936, c2, and P335. (Moineau et al., 1995)
  
• Encodes a restriction endonuclease that cleave the palindromic sequence 5′-GATC-3′ (Moineau et al., 1995)
