Ecori restriction enzyme

Ecori restriction enzyme

(Science: enzyme molecular biology) a commonly-used restriction enzyme (enzyme which will cleave the phosphodiester bonds of dna at specific nucleotide sequences) that came from the bacteria escherichia coli and recognises the sequence GAATTC.

The enzyme will make a staggered cut of the double-stranded dna molecule by cutting between the g and a on both strands.
